I love the fact that velocity is maintained between lives, that idea is really unique and executed well, leading to some interesting puzzles. The design is simple, but suits the game's atmosphere perfectly. I enjoyed playing this game. I had a problem when clicking next on each level; it restarted the level instead. To fix this, I just went to the next level in the menu screen.
A fun game, and a challenge to anybody who likes platformers, but also games that require you to think; the last level really challenged me.
Good job!
