Great game!The concept of the level changing with the timer is a bit basic, but the presentation more than makes up for it!My only issue is that, as cool as the boss fight with the crystal is, it does become a tad frustrating since it might decide to attack while you're about to touch it.Also, the sound design of the game doesn't really fit the visual style (even if,I admit, the crystal shooting its babies at you with the sound of a gunshot is funny.)
