Thanks for the thoughtful feedback! In terms of expanding it later, I think you're absolutely right. It was a challenge to come up with levels as is, and I think if I added many more I'd run out of interesting things to explore. (However, I noticed immediately after submitting that the way I wrote my code actually allows the player to go inside the cube as well if I made some sort of hole in the face of the cube, which could have been cool!) Thanks again for playing, glad you enjoyed it :D
