First of all, the music, it's very, very beautiful. Honesly one of the best musics I've heard in a jam game.
Even though the gameplay isn't anything revolutionary, the fluid and fast movement makes travelling through mazes quite fun.
The art looks really good. Very unique visual style compared to usual game jam art. If I have to nitpick, in some places (like in the pic below) it's quite hard to differentiate background from walls.The small story scene in the beginning adds a fine amount of context which I like.
Overall, polished and beautiful experience, well done Theo.
