Great idea for puzzle game. Really enjoyed the part where you push the cart in the past and see its wreck move in the present, just WOW! I can imagine a ton of puzzles using this mechanic. That being said, it is sad that we do not see so much puzzles here. The game features a few levels, which I would rather call a platformer with reality shifting than a puzzle game.
However, I greatly enjoyed it. The movement feels good. The visuals are simple but good looking. The intro cutscene is superb.
Good job guys!
