It's a fun little puzzle game! Clear visuals, simple controls, and some engaging puzzles made it enjoyable.
I'm not sure if I glitched the first red button puzzle, because I'm not sure if I exploited the player swap mechanic in a way it wasn't supposed to be used. If I get one cube through one gate, I can swap them to get the other cube through the same gate and it still gives me credit for both.
Very nicely built though! I think I'd play it again if you ever update it with more puzzles.
Thanks for reviewing my game already!
