I had a hard time attacking the enemies. Often they were just a tiny bit above or under the hitbox to get them.
And I struggled a bit with the double jump, i haven't found the pattern how and when i can double jump.
I really appreciate the details! The hitboxes are definitely a bit finicky. I'm planning to add an attack that goes below the player so that will probably help cover the bases for attacking enemies a lot better than the current version. The double jump part makes me realize that I never mentioned or explained the double jump in the how-to or anywhere else, whoops! Essentially you get one mid-air jump that resets whenever you touch the ground. So if you fall off or drop through a platform, you only get a single jump. I'll have to put something in the page description about that to help clear that up too.
