This is literally an ad maker, so I will permit advertising if you're advertising a remix of this project. (And thus, you can advertise your own game as well!) WARNING! There is a script that will delete your ad the next time the program is started that will have to be modified if you remix the program to run your ad. For a sample ad, go here to see an ad that my sister made using my recreational account. https://scratch.mit.edu/projects/246739194/
Funnily enough, I just got this idea from reading comments about not advertising on other people's projects.
