I found the idea very creative tbh, the fact that it also has a story that supports it is really nice! Most of my feedback will come from the difficulty though.
The image in the attachment bellow was the first challenge that really confused me, I felt like I had to Mario jump my way up while switching masks but the timing would always be off; eventually I did it but I stopped playing in a later level cuz it had a similar puzzle that was wayy to difficult.
Congrats on your first GWJ though, overall it was really interesting!
