Cool but a bit repetitive, I can see how indeed this would benefit from better puzzles.

Timing is a bit too demanding for my taste, I've never been a fan of puzzles that require a difficult execution: once I've brained the solution, I don't like failing to actually execute it just because I'm not fast enough or didn't jump far enough. For me Braid strikes a good balance: the puzzles are hard, but the platforming is easy.
