Unfortunately, the mod got trashed 7 times, and the user doesn't have their old Computer anymore. Also, the game was once uploaded on Newgrounds. but it also can't be found. However, a few images were archived in low quality back in 2018, but only Baldi, Playtime, It's A Bully and Gotta Sweep are in the pictures. The artwork for the Principal, Arts and Crafters, and 1st Prize is lost. However, it's confirmed that all three had artwork.
