I will admit, I played this while it was very late, but I need a lot of help in finding the medal. However! The premise is extremely interesting. When I was searching for 'Dog' on Level 2 my husband thought it could have been a Mars Rover. 😅 Eventually I did find the 'Dog'.
One more final push after some rest, or maybe a helpful hint will help me reach the ending. Even with only a single save function it works really well. Like repeated sessions or visits, almost.
