This was quite the ride. At first I was very unsure of what to do. Then I figured it out but it was not very rewarding to reach the objective in my opinion. The walking and running sound are very loopy, in such a way that it is a very obvious loop, this bothered me tbh.
I really like the drawings you did, and the appearing, dissapearing objects make for quite the show when looking around. The idea is somewhat there, but I think you could improve on the execution.
