Great idea, love the puzzle approach to a platformer. Really enjoyed it. Seeing the enemies during planning phase would improve the experience, and also being able to drag markers around after setting them. Deleting them and having to get them back from the sidebar can be a bit frustrating when you just want to move the marker a tiny bit. But overall well done!
