Ideas:
1: A skill that causes future skills to occasionally appear with brick tiles.
2: Skull tiles that hurt you when matched.
3: An enemy that changes the direction of gravity when attacked.
Can you add an option to disable anything score-related? (so that no score-related gems show up, there are no Dynasty/Indulgence tiles/pylons, and you don't show up on the leaderboard)
Better controls: arrows to move/jump, WASD to move camera, and space to attack.
