Here's a novel kind of casual game. Introducing: Gomibako (a.k.a Trash Box), a PSN game that's actually already available in Asia. The concept for this trash-compacting puzzle game came up during the PlayStation C.A.M.P. by one of its participants.
Check out these videos to see how it plays out. It may look weird at the start (note that this isn't played like a Tetris clone), but eventually you'll understand how it's played. I actually love the physics:
Now thing is, SCEA and SCEE still haven't announced it for North America or Europe, but according to Siliconera, there might just be a chance for it. For one, as you can notice in the videos, the game (as it is in Asia) is already in English. And secondly, they've uncovered a trademark from Sony, listing a Trash Panic.
Here's to hoping this game eventually gets released in other regions. It looks addicting!
