Not a bad game but I found myself getting stuck on invisible terrain half the time and I've noticed that when using a bow the path finding for my character went out the window a few times and he would try to run face to face with the enemy for some reason.
Also while playing as the miner I noticed that when I was trying to fire my bow at enemies on the upper half of the screen I would hit the skill button and well drop a pack of dynamite at my feet, not exactly a good design choice in my eyes to have the button up there able to use the skill when hitting space should be more then enough but that's just me.
