The concept, and gameplay works. The music is well complimenting too, I had a lot of fun playing! :) One thing I am unsure of tho is the colour use, background and foreground mixes together a lot, I think having even like a flat black background will make the game easier to understand. :D Other than that tho this game is really fun! Well done! 

I like the concept of the game, you just have to improve the visuals. Nice job

Cool concept and Idea, Some art on the blocks could of been done, but still, its a really good game!
