An easy straight 5's. I've no idea what witchcraft and sacrifices were needed to bang out something so polished, fun, creative, and on-theme as this. Honestly on the level of full-fat releases. The little reflection of the elevator as it descends, the SFX, the little transitional animation details, the sheer balls to ask the player to not only complete a level, but on their own schedule. Like a cerebral Hotline Miami. Incredible and I hope this is a featured title.
As an aside, crazy cool shaders used here.
