Enemies can shoot through walls on occasion.
Weapons sets that have been equipped seem to be randomly carried over or set to the default on level change.
Orc helpers are randomly killed before the level starts, I thought it was ambiance until I restarted a level to end up with a living one.
Clipping occurs too often.
Functionality buttons are a little crowded, may have gotten used to it if I cared to get past lv4.

Needed more play-testing to be a viable source of entertainment.
