The moving wall idea is a really good idea! I wish I thought of that.
This game jam was my biggest game jam project I've ever done as it was the first game jam I did that used sprite sheets and levels (yes levels). Specifically with the level design I had to make the system myself during the jam and didn't make it well enough to create levels quickly. I got done as many as I could but there was much I wanted to add that I couldn't.
Thanks for the comment! It was really encouraging! (Also the little guy with the cape is supposed to be based on the player in Tomb of the Mask ok bai :D)
