Mega Mash: 7 in 1 Game Cart
From Nitrome, creator of Final Ninja, Test Subject Arena, and a few dozen other grand browser games, comes Mega Mash, a game that is sort of seven games but is really just one game (does that make it eight games?). The gist of it is all of these games are interwoven due to the buggy nature of the cartridge they're on. Instead of playing one or the other, you hop between them, using abilities from one to clear a path to progress in the other. Unusual? Yeah. But it works better than you might think!
Mega Mash starts off simply enough with Carrot Story, a very Mario-esque platform game where you hop around, eat carrots, and stomp enemies. When you reach the end, you cross a fuzzy barrier and glitch into Xolstar 3, a space shmup. Shoot some asteroids for a bit and you're back to Carrot Story. Then, you could end up in the Bomberman clone Blast-man Joe, grapple around some buildings in Ninja, or get thrown into a game of Nitrometris. It's usually fairly obvious which genre you'll play when you see the foamy barrier, and you can hop in or out as easily as you can press a button on the keyboard.
Mixing so many different genres into one game is dangerous, but Nitrome did a good job integrating puzzles from one into another. Push buttons with the ninja's grappling hook so you can switch to Joe and open a passageway, for example. You're always working towards a single goal, no matter the control scheme or visual differences, so the transition is never jarring. And if you're not particularly skilled at one of the game types, you can usually fudge your way through without much of a hassle.
Creative, good-looking, and retro enough to make even the most nostalgic of gamers shed a tear. Mega Mash is one glitchy game cartridge you won't mind firing up.
