This is a fun little game! It's neat you were able to involve your students and I enjoyed seeing what all random objects and places I could find (the Minecraft dirt block was probably my favorite find). It felt very cohesive. The cheat codes were quite fun to play around with.
One potential bug(?) that I didn't see mentioned was I would sometimes hit an invisible object that would end in a RIP screen. Maybe it was a world border? Not sure.
Overall a fun little game, I liked all the strange worlds and objects, cool take on the theme!
