Thanks for checking it out, and I’m glad you had fun with it!
The progression is roguelike-ish: each run sends you into procedurally generated caves with branching routes, and between runs you can visit the shop to improve your broom, hat, and permanent upgrades.
The caves keep getting harder the deeper you go, so it has an endless-runner structure too. Eventually the cave will get you, but the goal is to push farther down each time and build out your kit along the way.
