What time is it? Tasty Planet: Dinotime! Mathematical! The popular action series from Dingo Games is back, and this time things have gotten prehistoric. Like always, gameplay is one part Fishy and two parts Katamari as the ancient world faces the cutest darn grey goo scenario you ever did see, and you have the starring role as the goo! It's eat or be eaten as you grow from pebble-size to apatosaurus-size... and maybe just manage to do something about that huge asteroid in the sky.

How often do you find yourself playing a game and cackling: "Fools! You've only made me stronger now!"? Not often enough I'd say, but developer Dingo Games has set out to rectify this problem with its game, Tasty Planet. In this preview version of Tasty Planet you take control of a microscopic ball of grey goo. Designed by scientists to clean toilets, it soon becomes apparent that this goo can absorb anything and grow without stop.

For some reason, everyone loves collecting things that are smaller than they are. We're not so much interesting in gathering buildings as we are looking at them, but if buildings were pint-sized, you can bet they'd fill our pockets like lint-covered jellybeans. Tasty Planet: Back for Seconds plays on this compulsion and puts you in control of a blob of gray goo that can eat anything smaller than it is. As you can guess, this is a dangerous thing to let loose on the Earth, but give it a time machine and all of the past and future could be in quite a pickle.

Sentokun in Kamakura is a short 3D action adventure about a monk with antlers on his head, on a quest to defeat a giant, antlered cowboy. At the beginning, the monk is too weak to prevail, so to build up his strength, he must ransack a peaceful coastal town and raze it to the ground. If you liked Katamari Damacy, or you wish there were more browser games that let you throw houses at people, you may enjoy this.

The Wonderful End of the World is an off-kilter, Katamari Damacy-like game where your only goal is to pick up random junk scattered across the world. Terra, the goddess of the earth, knows that the world's inevitable doom is coming, so she uses a puppet on the earth to collect as much stuff as she can, for rebuilding the world later.

Eater of Worlds is a stylish side scrolling action game with a fun little twist: you're a blob that absorbs everything it comes in contact with. From fish to seaweed, cats, trees, humans and trucks, the world is your buffet and you're ready to eat. Gather as many objects as you can across the game's three levels and see if you can secure a space on the high score board.

Fizzball is the latest game from Matt Parry and Ryan Clark of Grubby Games—who gave us the perfectly adorable Professor Fizzwizzle. It was described to me as "a combination between Breakout, Arkanoid, and Katamari Damacy," which pretty much makes it compulsory playing.

An official Katamari Damacy mini-game is now available on Namco's Japanese website. It appears to have been designed to illustrate the main concept of the game, which is to joyfully roll the katamari over smaller objects to collect them and make the katamari bigger so that you can then roll over even larger objects. To this end it works quite well; however, the mini-game does not even come close to the fun of the original.
