The game looks good. Big respect to the person responsible for the sound — excellent work. The limitation was used... in an unusual way? The game is visually appealing (for some reason, I kept getting Lona RPG flashbacks).
The heavy crossbow is the best weapon. Honestly, some weapons feel unusable — for example, the axe (I think?) that hits three tiles away from you. It has a really long cooldown, so enemies have time to eat you while you're aiming.
The bugs were a bit disappointing: on the second level, I couldn't tell if there were any walls, and I got stuck inside enemies a couple of times.
Overall, I liked it. I just wish it had more roguelike elements, like randomly generated levels.
