Very cool concept. As others pointed out, the controls were a bit confusing, but once I got the hang of them, I had a lot of fun! I would definitely change the arrows to be relative to the screen, not the mouse, to make it more intuitive at first. The yellow/red spots in the fog are super helpful in guiding where to break walls, and I love that I was forced to break in from different places. I think these do wonders for creating a fun experience.
Pretty strong submission, good job!
