Simple concept, and though the levels were a bit too on the simple side I can appreciate the gameplay mechanics of switching between the two angels. However, I'm too used to using the spacebar to jump... this resulted in me dying tons of times to regular spikes that could've otherwise been avoided easily. I would recommend not using the spacebar for something like that or adding an ability to switch control schemes!
The art style is rough around the edges, but if polished up a bit I think it'd look quite nice. I think it gets the job done. Keep making games!
