I think my monitor calibration is way off, at night my screen was black.  Having screen calibration would be helpful.

This was on the harder side to play for me because of the screen size and the color swapping started to hurt my eyes after a few minutes so I had to stop playing. I enjoyed the art and sound while I was able to play.

I like the concept you went for. I think if you added more time between switches and made the big form invincible it would tie everything together quite well (run while small and strike fear while big type of deal). Good job :)

day and night switches so quick. maybe add some more seconds there and a sound that indicates it is switching soon(like a countdown sound with increasing or lowering sound), so the player is more prepared when the switch happens so they have time to move to a good spot.
