The idea is interesting, but it's hard to know what to do because there are no control instructions in the game. I wasn't able to shoot or use abilities either, so I couldn't make it past the first level.
The shooting is broken, we didn’t finish it in time :(
Some tips on jumping: you have one jump that is reset whenever you touch a safe surface.
Try walking off the ledge then jumping as you fall to get more distance.
Or jump after you hit a ceiling.
