This game is genuinely great! I dreamt the other night that I made something very similar to this, glad to find someone else already did it for me. I love the soundtrack and the art. I love the DnD 1e style difficulty. A minor critique I have is that spells and attributes seem to be ripped wholecloth from DnD, whereas I would have preferred something more unique, but it's not really an issue; it means that I know roughly what everything does going in.
Congrats, I can see myself spending hours on this one ^^
The mechanics behind stats/classes/spells were based on Basic Fantasy. Since it was made for a game jam, I decided to use something open source as a way to keep things familiar for players and have a semblance of balance.
