I really like the combination of dungeon crawler and tower defense! The graphics were nice too, but I agree witht the comment about using the wrong texture filter on some of the sprites. The players hands especially look blurry instead of pixellated.
The lack of a tutorial I think also hurts this game quite a bit. Like even from the controls list on the game page it took me a bit to figure out I needed to select an item and THEN press F.
You already listed the getting out of bounds bug, so I'm certain that will be fixed.
I think this was a great entry, it just needed some more explanation of the mechanics.
Good work!
