Thanks for the feedback!
I didn't think there would be problems with the spikes, but I'll take that into account.
Double jump is a bug lol. It works when you are near an object with a wall tag (If you go to the wall at the beginning of the level and jump, you will fly into space).
As for the range, I'll try to do something, but there's a high chance of breaking all the enemies. Their code is so clumsy that I'm surprised they still work.
