You don't really need the double jump there I believe, all you have to do is jump right left right left. Yet I definetly see your point, will attempt to fix it i guess. Although as mentioned, I'm really bad at coding so I might not find out why the jump doesn't register.
Also I fixed the bugs you noticed, the enemy stuck in ground was a really bad placed collider and the jump was to add to the challenge but if it is really annoying I might just remove it. About visibility, I will attempt to increase the camera size. Thanks a lot for the feedback though, it really helps me.
The new pack should have fixed most of the things you mentioned. The rest will come post jam >.......<
