There is something really pure about this game that I really liked. The simplicity of it combined with strong nostalgia feels for me (I played crawlers with a similar aesthetic many decades ago). Also thank you for including the map, this isn't a game that I would consider particularly playable without one. For this title I think BFXR would have been a great choice for audio.
I encountered a Wyvern when I had 26 health and despite casting death spells every turn until I had 3 health, then trying to run away for the next three turns I still ended up dead.
My suspicion is that you can create a lot of quality content from this engine.
