Such a fun and complete game. Music is on point. The graphics are neat, easy to read while playing. The only thing I would say is that there was I think a few elements that didn't quite fit the pixel art style like the golden key.
Yes, some of the UI art was from a different art pack and we ran out of time to create our own replacements. They were the best visual representation we had ready, so we went with them anyway, but if we do further work they would certainly be replaced.
