Excellent presentation. Loved the music. Fantastic game. To provide some feedback, I wish there was more decision making at the end of each fight like what loot to take or something similar. Finding loot other than materials would be nice as well. A death in the dungeon would have much more consequences if I lose a cool sword I found.
Hope the feedback helps! Hope you build upon this idea as I really enjoyed it. I got some Death Loop vibes for sure.
