Hi, sorry you ran into a few bugs. But for what it is worth some of the things you mentioned just are not a thing in the original game.
- Mobs never ran out of energy or even used it.
- There is no lantern on the gate, it's just an image in this game due to how that image was acquired
- Stats only increased by items, you never got stat increases by leveling up
- Lots of the things like the armor and stats just work that way in the original, the wolf boss is ironically always been the hardest to kill
So for that reason, bad design or not I wanted to include them, things like the stacking is a known issue and have been fixed in the upcoming revamp of the whole game I am working on. I will look into items being able to be equipped before their level though also.
Interested to know how you broke the game though also?
