There were going to be some additional traps and maybe flying enemies, but we simply ran out of time to make that work. The hope was to get an attack move going in the 11th hour, but we decided placing some coins and such to guide the player was more feasible for the time we had left.

Yeah, the wall rocket was an unintended mechanic: I had been planning on doing some simple raycasts to figure out relative positioning and then push the player away from the wall, but ran out of time.
