I really liked the puzzle aspect of your game—specifically, having the different slimes give you a unique ability needed for dispatching the next slime. However, I'd be curious to see how your game would play differently if the platforming controls were a little more dialed in. I thought the wall jumping was difficult and the overall jump felt maybe a little more floaty when compared to other platformers in the space. There were also a number of times where I thought I'd make a jump, but I'd fall down instead because my timing wasn't perfect enough. Giving the player more coyote time (or implementing it if you haven't yet) would really help here!
