I had a game like this on the orignal gameboy where you played as mario and had to carry a key and solve puzzles! Your game brought me back to the good days where we can only carry one item at a time! I very much so like this mechanic and these types of games. To be honest the Gameboy seems like such a great platform for puzzle games like this!
Great work on this one! Would love to see more levels and carry more objects over my head! XD XD
