Inspired by Bit Blot's Aquaria, Duncan Fenn brings you underwater, metroidvania goodness in Aqua Boy. Betrayed by your simian companion, you must explore a dangerous, aquatic city in search of your lost equipment so you can find your monkey traitor and make him pay for his actions. A relatively easy title with a hefty map, Aqua Boy will keep you pleasantly occupied.

This sub mission was a fiasco from the start, but if you could have said no to your Nazi commanders you wouldn't be spending December 1941 in the depths of the Atlantic. And there are... things out there. Subbania is a metroidvania-style action-adventure by ektomarch, where cosmic horrors lurk in the depths. Quite unsettling and atmospheric, if a little stingy on save points.

A lovingly detailed homage to classic platforming adventures, this retro-styled Metroidvania game takes place in a post-apocalyptic wasteland where your only reason for living is suddenly abducted from you by a mysterious stranger. While it could use some more to do, it's a beautifully made title fans of classic gaming will enjoy.

A simple errand takes a turn for the surreal when our hero, forced away from the video game console and out of the house, stumbles down a hole into the middle of the earth where he is, of course, tasked with tracking down magical gems. The same thing happened to me the other day. A little bit retro, mixed with a healthy dose of metroidvania and high-difficulty platforming, and Kodachrome is a weird but appealing little challenge.

We all love metroidvanias! But would we still love them if, instead of controlling a scifi bounty hunter, or a badass vampire slayer, we played as the alphabet? Answer: Yes! And ASCIIvania, an exploration platformer by Gharding3, is the proof! ASCIIvania is clearer documentation, a map screen and a mute button away from excellence, but its still a fun time.

First released in 2008, The Power was a behemoth of a Metroidvania-like shooter for downloaders only. Now, The Power is back and available for your browser pleasure! Search, shoot, and upgrade your way through a massive world to discover the mysteries of The Power, and why it's so important to a strange planet.

Fans of Metroidvania style games, rejoice, and put on your virtual sneakers! SubMu entertainment's latest release, Blockstachio, incorporates quirky, blocky graphics, and a soundtrack that solidly consolidates retro bleeps and bangs over the top of the heroic theme music that will drive you towards your goal, while also packing enough platform action to keep you happily satisfied, while running and jumping your way through each level, in your pursuit to save the world. The world needs saving, and it is up to you and your cubic hero to do it. Are you up to the challenge?

Arzea is a Metroidvania-style adventure game that demonstrates the kind of danger that magic can lead to. You're a wizard stranded in a strange world with only your wits and a variety of spells and upgrades to help you get home. Your main goal is to find your way home from the strange land of Arzea. There's at least a good half hour of gameplay here, probably closer to an hour if you're out to find all the upgrades and collectible shards.

It's a popular misconception that cats have nine lives. In reality they've actually got infinite lives and are forced to restart at checkpoints every time they lose one. Katwalk is a short, fairly easy platforming metroidvania game, so aside from one tricky section involving swimming you won't need catlike reflexes to succeed.

Damian Sommer created this short, no-frills little puzzle platformer to throw the player into a series of one-screen, "extremely distilled metroidvanias." He accomplishes this by first teaching the player some rudimentary game mechanics and then builds upon those rules incrementally while increasing the difficulty and complexity of each level's design. And it works quite nicely for a game made in just a day and a half.

Pedro and the Pearls of Peril is the kind of game that's likely to have appeal to multiple demographics. First of all, there will be those in the mood for a good action-shooter, with some shades of Metroidvania and a masochistic edge of difficulty. Then there will be those who'll be convinced once they see the name of Robot Wants retro-maven Hamumu on the title screen. There will be those Cub Scouts who just happened to stumble over the game on the Boys Life website, and are intrigued by what wacky new adventures Pedro the Mail Burro has gotten himself into this time. And last, but not least, there is the not insignificant group of gamers who have a thing for alliteration. Never count them out.

The hermit's son has been kidnapped by demons! Are you a good enough king to rescue him? And, while you're at it, could you do something about that advancing purple wall of doom? And, also, could you tell the peasants to knock it off with all the portentous statements concerning the upcoming apocalypse? Sigh... It seems that a monarch's work is never done. Though by the end of KingStory, the new adventure platformer from KintoGames, you'll at least have a pretty sweet crown on your head. That makes it all worthwhile.

Developed for Something Awful's GameDev VI Challenge, the retro metroidvania platformer Psychopomps puts you in the shoes of Anubis, who has overslept. In his absence, his fellow soul ushers have gone missing and evil spirits have grown powerful. Explore your environment and shoot down your enemies as you rescue your friends and right the matter of directing souls.

Twenty years after nuclear confrontation wiped out the planet known as Earth, Cosmonaut Laika receives a distress bark from the ruined surface.

Every dog has its day, and today is the day you... Escape from the Puppy Death Factory! Brought to you by Arthur Lee and the fine people at Adult Swim. A fun, if deceptively challenging, puzzle platformer.

An excellent metroidvania style puzzle platformer that's easy enough to jump straight in, but has a ton of hidden secrets for experts to find (especially if you want the best ending)... along with a few locked doors that just beg for further expansion. Legend of Kalevala has that perfect mix of old and new, alien and human, story and action.

About as epic as any game about snails can be, Snailiad will take hours from you, and you'll be glad to see them gone. It's action-packed and adventure-filled, completely unlike the lives of real snails, who mostly sit around hoping they don't become escargot.

Everybody's favourite emotionally tortured little robot is back in this sequel to 2010's K.O.L.M., a Metroidvania style platformer about a lonely little robot with one very dysfunctional family.

You wake up alone and abandoned in a cell, with no clue as to the big W's; Why are you here? What's going on? Who are you? This short little puzzle/platformer is a moody bit of storytelling from KrangGames that shows sometimes you don't have to say a word to tell a compelling story.

Everyone's favourite sad but earnest little robot is back in a set of time trials. While it might lack a story, the spiritual successor to the original K.O.L.M. definitely does not lack a challenge.

Insidia, the new Metroidvania-styled platformer from Woblyware, revels in its simplicity, not only concerning its graphics, but also is its plot and gameplay. In fact, I think that I can give you the gist in fifteen words: Crashed Spaceship. Alien World. Explore Caverns. Find Repair Kits. Collect Upgrades. Avoid Baddies. Quite Fun.

But an unexpected tumble drops you into a whole new world of possibilities. Will you be the hero, or will you bring the darkness? More importantly, who can you trust if not yourself?

Help a little robot get his life together in this melancholic Metroidvania platformer from Tony (Antony Lavelle) of Armor Games.

What's not to love about this fantastic sequel? The kicking retro graphics, the astonishingly nostalgic music and sound effects, everything adds up to tons of fabulous casual gameplay. Enjoy the new challenge, the new enemies, and the same fantastic warm feeling as you help your lonely robot find yet another friend.

When an earthquake leaves Jack the only survivor of an expedition in Mexico and strands him underground, he'll have to find his way out alone. Unfortunately, in addition to having some bad luck, Jack also doesn't have any legs, forcing him to find different ways to circumvent things that would barely slow you down in a typical platformer. Made in a month for Something Awful's Game Development Competition and inspired by Super Metroid, You Have No Legs is by turns frustrating and challenging, but undeniably creative and worth a look.

Robot's at it again; armed with a kitty perched atop his boxlike head, he's off to get himself a new friend in this follow up to the surprise smash-hit original retro platformer.
