Right, so...
The game looks good, but controls feel a bit weird. I am not sure what's wrong with it, I just didn't have "I like it" feeling.. Shooting: if you walk + shoot, sometimes arrows will lounge a bit off the grid, dealing damage to the enemies anyway..
I found it difficult (probably because of combinations of enemies..)+ challenging. Smart way to make a menu as you did, liked it!
Overall, good job.
