Additional puzzle elements such as switches, blocks, and gates introduce more complexity during gameplay.

Reception

Eurogamer wrote "At less than the price that airports charge for a packet of Extra, Quell is yet another way to make you feel Zen about spending hundreds of pounds on Apple hardware".
