For 11, this is great work. I could not have conceived this at that age, so really impressed. I did run into a couple bugs, one main one being that I fell into the mines and could not escape. Had to restart the game to continue. I also think that the various different art styles included kind of clashed, and would recommend trying to unify them in some way in the future. Either way, excellent job for a first jam, and excited to see what you make in the future.
