I actually beat this! I had a lot of fun just walking around and taking in the environment, I know you didn't create it, but it's still cool!
I didn't stay in bounds, I constantly took a quick look outside of the map to see where to go, but I liked the fact that this was possible, it made it feel like I could beat the game my own way instead of the intended way, allowing for more freedom.
I also didn't press Exit, I just walked off of the map, which was fun. The "Being in space" was also a surprise
