A platform puzzle game like Fireboy and Watergirl where you control two characters with different directional keys and you have to make sure that they work together. Your dog Mor is strong and heavy so he can break boxes and push down stone walls. He can also swim but Pheus can't so he will have to ride on Mor's back while he swims through water. Pheus is smaller and can jump to reach places that Mor cannot. He will also a lot lighter than Mor so he can climb up areas like a see-saw and hit a switch that will drop a box to help balance the weight of Mor out so that he can run up the ramp.
