Press the green flag, and see what wacky and random custom entity you will get! Yeah, you can pump out your goofy entities! More will be added in the future. In all seriousness, this project might be good for some entity inspiration for a fangame. You can also see a randomized name at the top of the screen, you can tweak the range of numbers if you want. This does not give custom mechanics, if you want to have custom mechanics you'll have to think of them yourself sorry.
'Rooms' on Roblox is created by nicorocks5555, so credit goes to him for the original game. Some face randomizations are inspired by games such as Interminable Rooms and Rooms: Low Detailed.
