I am sorry,but this games is cancelled (Bad News)

You, still can play the game by downloading it, but I am not working on it  here's why:

I was adding a new feature to the game including better lighting, to make it look realistic instead of looking like and 2001 game, so I made the changes

and saved it, the next day I open my game/project but it didn't load, and it showed me an error that said I never ever can't open my project again. There were no fixes available, the only thing I could do is report the bug. Rip non-named-game/Sandbox game 2021-2021 ;(
