Great idea. It is a shame that it was too big for this game Jam. There were a few annoyances. When you pick up an item in the sub-game to take outside and accidentally crosses your player character, it takes the item regardless. While that could be intentional, since it isn't actually useful, it feels more like a bug. The spikes in the dungeon where also weirdly unforgiving, forcing to restart the level. Not being able to move diagonally made the controls feel unresponsive. Lastly, I have no idea what you wanted me to do with the 100 coin door, except literally grinding. Maybe I missed something, but the solution was not clear to me.
