Nice entry!
I just have some comments/suggestions about the game:
- There are some performance issues because I got some FPS drops in the game. My PC is not that good but it managed to run perfectly this another entry (https://itch.io/jam/lowrezjam-2018/rate/293403);
- The HUD could be a bit more compact. You're using 8px of height for HP and MP stats, you can do it in a better way using only 4px. This will adjust the contrast between HP/MP and the weapon icon. Also, the HUD will look better on the top of the screen because it is currently hiding the sword;
- There are some issues navigating menus, especially in the inventory menu. There's a bug preventing the buttons from being focused.
