I thought the concept is simple, but it works for the jam. The environment is pretty detailed for how little time we had, so kudos for that!
The tutorial and settings buttons on the main menu don't do anything, I'd have them removed. Took a few tries until I understood how best to move, it was a bit slow but not too bad. I did struggle to find exactly what to do after I reached the marked areas, I felt like a tutorial was very needed. I did get a chuckle from the quit pop-up, would have loved to see that snark in the main game
