Very creative! I used a similar size-changing mechanic in my game.

Fun game, and pretty challenging. Being small helped but didn't avoid damage all together.

Pretty simple, but enjoyable. I didn't find the need to get bigger, but still being small adds some complexity

Good game, graphic could do some work, also i would say the smaller you are the better and didnt really find need to get bigger, score should go up only when you pick up coin, not just by time survived. Maybe add multiple sizes of coin and if you are too small to eat it you cant, that would give incentive to became small and big. Overall good game. :)

simple game, but fun and creative ideas!
