Thanks for playing and for the detailed feedback. Really appreciate it.
I agree the stamina is not clear or well implemented yet, which has been raised by others. I find it frustrating myself. I also feel the tunnels are just not fun yet -- too large to explore and no story stuff in there yet. Combat could use some additional work too.
The amulet you're supposed to put on, and once you do you can speak to the skull in that room (unless it is missing). Seems this isn't clear, perhaps I need to force equip the amulet once you pick it up.
I'll try and give your submission a play before the voting ends. Unfortunately I am going through a lot of personal stuff at the moment and it's hindering what I can do around this jam. But again, thanks for playing and for the detailed feedback.
