Run, jump, collect coins, and solve puzzles — on multiple platforms at once!
Hello Worlds! is one of those wonderful games that's super-easy to learn (arrow keys to move, space bar to enter doorways -- done) but complex enough that you can spend an afternoon playing. ... The point is to grab the gold coins while moving through one, two or even more worlds at the same time -- and even if you can't see them, the obstacles in one world affect all the others. (Start playing, and after a few wrong turns it'll start to make sense.) Amazing, right??
