You’ve got an interesting foundation here. I managed to get the jump/jet, which was fun. Although I don’t think you intended it, it was amusing to click to go the (empty afaik) boss room. I don’t know how you’re supposed to get the hearts after getting the jump, there is one enemy you can’t jump on at all. I tried to get higher up but always eventually died, this area was especially hard because the camera was so close and the jump is so high.
