Taking a break from TL2, I started up Tiny and Big and am already 2/3 of the way through. It's pretty fun, the ways that you can manipulate the environment are enjoyable, if somewhat limited. And surprisingly, the story about the underwear that you wear as a hat looks like it gets pretty dark.
But level 3 can just bite my ass. You have to get through it with very little environment manipulation, with huge boulders being hurled at you the whole time. I have no idea why they thought that was a good idea.
