The controls and mechanics were very confusing. The controls for the top player should have been at the top, and the controls for the bottom player should have been at the bottom; putting them on the left and right was very unintuitive.
I honestly have no idea how the teleport mechanic works. I don't know if I perma failed the level, if it was winnable, if the game was glitched, or something else; but I got into a situation where I couldn't progress.
The main mechanic felt interesting, but if I were making this game I would put a heck of a lot of time into the tutorial section. I would make the first bunch of levels a tutorial, and not leave it to a text screen at the beginning (seen once and then never again).
