I really like the idea, but I think there's a bug with input for fixing bugs (ironically), like i press the mouse left/right button and it doesn't fix any bugs, if i spam it sometimes registers though. Maybe you are checking for input in FixedUpdate? If that's the case then move checking for input into update (fixed update runs on fixed period of time, if your button press doesn't fit into that window then it won't register). Also I would recommend adding a physics material 2d with firction set to 0 on the player, that way we won't get stuck on the walls, would feel better.
Still for your very first jam game it's really cool, I also loved the intro lol.
