It might be good to make the Confirm Layout button stand out more when you have a valid dungeon, and when you're in the dungeon movement feels very slide-y and hard to control for the number of enemies/projectiles on screen.
A fun and interesting concept. Though the controls feel like they could be improved, the lack of a soft-drop, slide-y feeling of the pieces, and near-instant lock time make it hard to do technical maneuvers like T-Spins
