Extremely polished, but very difficult to control. Level progression flows bad and difficulty spikes hard. I get maybe you want it to control like Celeste or some other difficult platformer, but you gotta start easy, even if just for the first levels :\ maybe make slo-mo button configurable or activate separately than the swap key, would make swapping easier because I end up pressing just out of reach of certain objects. If not just increase swap range or have objects not as far from the player?
