The game is really smooth and has a really nice take on the parallel theme, the controls felt janky at first and I had trouble understanding, but got hang of it eventually. The sound effects were satisfying, some ambient music could have helped, but I don't actually think that it's really necessary, I just really like music. The graphics is really helpful, with highlighting the walls you are currently one, That's a really valuable guideline throughout the game.
Overall, great job!
