I love this top-down games so I might be a bit biased :P
I liked the mechanics and the time I spent killing orcs was pretty fun.
Some things that I found were a bit confusing:
- Both player and orcs can get hit by their own axe. I hit myself many times and some orcs also killed themselves (pretty funny actually).
- There was no cooldown indication for attacking so at the beginning I wasn't sure if I had run out of ammo or just the spacing between attacks was really long.
I saw that you already mentioned the lack of time for implementing things. With them I'm sure´it will be a pretty solid game. Good Job!
