Ok that was actually really cool! I finished it in 125 turns. Very unique and a very real twist on the jam theme. I also I see you did EVERYTHING your self including the sounds, super impressive. This honestly with a little more polish and content could turn into probably a good roguelite or something.
One big issue I had though was just learning the game. I read your description before hand, but when actually playing the first battle I was so confused. I think at one point I killed the princess as the goblin and I think it gave me a game over (I might be mistaken on that though) but from that I was so confused, and tried for another 3 - 5 minutes trying to figure out how to win against the goblin or at least proceed. Maybe I'm just tired, but I think an in game tutorial or a really obvious enemy (like one of those orges that have a ton of hp) may have helped cement the idea of what to do. I almost quit at that point and then checked the comments here... but no one else seemed to have that issue so it could have just all been me.
But once I figured that out it was great and I ended up beating it! Again the above may have just been me being dumb, but other than that I thought the game was really great and cleverly thought out (not to easy or hard). This is a great entry into the jam! Great work on this!!
