Cute game, i really like the style and presentation of it, the main character being a "Cool square" is executed really well, for a heavily rushed game it has some good puzzles.
as for feedback, the shifting camera doesn't quite work for a game like this where the edges of the map are important, while i do like it as a stylistic choice it's not the right place for it, same goes for the red square following, when it snap around it looks a bit off
finally i would have made the entering the exit door automatic, for speed and such
good job!
