Great stuff! Love the AI and the sprite work. It is a bit difficult for me though, haha. A few comments:
The weapon durability is interesting. It encourages trying out new weapons but can be a bit frustrating at first.
I kind of hate the shield guy. There is no way to hit him aside from waiting him to become tired?
And lastly, I would like to go between rooms just straightaway instead of having to interact.
Hope you found this useful!
