Gorgeous animations and backgrounds. I get quite a "Dragon's Lair" vibe from it. The only point of criticism I have is that it forces restarting from the beginning whenever I die. While it increases play time, it also makes experimentation later on in the game a bit more difficult. Fortunately, it's not too long, so it's a minor niggle, but if you end up expanding on it after the jam, perhaps a checkpoint or save system would be useful.
