Graviton

Wow the game design here is not messing around -- it's very, very challenging but it's the fair kind of challenging where you bang your head on the desk but then finally get it and feel like you just climbed a mountain and yeah maybe you're crying but you throw a little party for yourself and everyone's invited but look around, it's just you, but that's perfectly okay. Graphics are clean and basic, it's clear the game is about the puzzles though. They seem very simple on the surface but they can be actually very devious and clever. Once you start realizing what the game is asking for, you start getting a feel for the levels and you can actually move through the game pretty smoothly. There's a "skip level" feature if you really get stuck and just want to move on, but they're limited. You can earn them back by beating the levels you skipped, and there's some sort of life-lesson in there I think. Something about going back to confront the emotional demons that tormented you in the past...

Great game. Great logic puzzles. There seems to be one BUG. It crashes when Steam is in Offline mode !
