Wow. Nice game. The way it looks make me think it was made in phyton from absolute nothing... Anyway, the game looks awesome and I really liked the concept. 

Fun puzzle game! The scoring mechanic is great - it feels fair and also quite dynamic.

Very simple, but well made! I liked how the graphics changed from time to time. The sounds and "animations" improved the game feel. I think the blue tiles bugged after the first or second level up, they had squares instead of animal faces. I got to 514 points.
