Nice game! It's easy to understand, short, yet very fun to play! I think topping it off with some music would be amazing!
Level design is simple yet addictive, it makes you always feel like you are about to win... but are just missing something; and then you figure it out and it feels so good!
The whole game is very simplistic yet still fun and enjoyable, the art, and SFX fit well. One note though; Sometimes it did feel like the controls weren't responsive.
Overall:
(0 being crap, 100 being triple A)
