That's awesome you're making all of this by yourself. Overall the mechanics are all pretty solid, which is great. I loved the use of camera zooms when I died, it was an enjoyable touch.
I found myself clicking a LOT. Maybe there's a better way to do motion, like holding the mouse down to continue walking or something?
I think the upgrades could have been a bit better as well. You start out pretty weak, so it'll be more fulfilling if when I get a couple blacksmith upgrades they feel a bit more substantial.
