For entirely non-RTP graphics done for a jam, this is rather good! As you say, got significantly easier towards the end except for the final boss. Like the "hop over gaps" and "choose a character" mechanics, but wish that I wouldn't have to play over and over to see all the final farewells. Only bugs that I noticed were some water & walls were passable, and that there didn't seem to be a Pristine Channeler weapon.
clean game with well-executed concept. the mechanics were smooth and easy to pick up on.
