Hi, I am the Game Designer for this game.
Thank You so much for your feedback. We didnt intend to make combat for this we just found that particular character sprite that suited our game atmosphere and it just so happened that they also had a sword. By the way u can lure the goblins to the mines to blow them up.
We didnt have much time to test it so didnt know what should be the exact amount for the exit toll, thank u for your feedback about that,
We will try to improve in future this was my first jam so i thought to keep it a little simple.
