Art and music are out of this world! I think it's possible to get stuck right after you get the slide if you go to the right and down into the room with two frogs, if that's the only ability you have you can't jump out again. I just restarted so not a big deal. This is quite a difficult game. Sometimes I would clear a room and enter the next, and then the knockback from an attack or taking damage would push me back into the previous room to be surrounded by newly respawned enemies and they would mob me to death. The knockback is also tricky in the parts with moving platforms over spikes, the flying pigs treated me as their volley ball and literally spiked me lol. Great job!
