Crayon Physics Deluxe
 

I was randomly looking around for portable USB games and stumbled upon a site where a guy was creating monthly games. Then I noticed that he wrote he wouldn't make anymore until he was finished with Crayon Physics Deluxe, I went to check it out and it apparently had just some out. So I watched a video, downloaded a free earlier version of it. Beat it with only boxes (It's harder than the real game). So I bought it and I've been very satisfied. Look it up yourself, there's now a Crayon Physics Deluxe demo, I think you'll like it too.
