Undistortion Line

Unfortunately, this game has been left unfinished due to some unforeseen circunstances having prevented me from doing the last third of the challenge. It is fully playable, it just doesn't have sound or a tutorial.

This is a simple game. Your job is to watch the little squares move through the conveyor belt and make sure they are, well, squares. Unfortunately, some may be a bit distorted, as an image in a convex or concave mirror might be. 

Fortunately, you can do something about it, you just need to input the right command. Be careful though, you can only interact with a square once and you lose if you let even one messed up square pass.

Controls:

Left Arrow -> Fixes wide "squares"
Down Arrow -> Skips squares
Right Arrow -> Fixes tall "squares"

Have fun!
