I like the idea of the double body. I find it very stimulating to have to control the "push movements" in relation to space; when many enemies pile up on the screen things get interesting. In this sense, the Super Mario stun helps to gather a few seconds to think. The use of cubes as score (and the only way to continue) forces you to use weapon other than your favorites, and this is good. But when saws happen, I do hell!
Eyes squints before releasing the jump are adorable!
One note: I would have made it possible to get on the platform when you are close to the edge.
