Interesting game mechanics with good use of acceleration and deceleration. Good use of puzzles and strategy within the level design. Nice replay footage, similar to that found in Super Meat Boy. My only criticism is the music; it is repetitive annoying. Good job.

this game could of done with more work; giving the player things to spend the money on, the game play felt jolting and not fast-paced, more work on the art of the game. However, it shows that you have good ideas and concepts for games, develop this more and it could be a hit :)
