I think I need to introduce the enemies in another level, because the player should be able to tell that they can't jump over them (because of their jump height). The solution is to get between them, walk with them, and then warp.
Two solutions come to mind if I can't solve it by adding levels before that one:
- Taller enemies
- A ceiling that restricts jumping, so the user wouldn't try that strategy.
Thanks a whole lot for the feedback!
