"Grand Dad Mania Revived" uses assets created by the original Grand Dad Mania team.
That original project in turn used assets from the SiIvaGunner video "Trailer Theme (In-Game Mix) - Sonic Mania".
The original authors of these assets do not necessarily personally endorse nor disapprove of this project.

Note: the game is still very much in development. However, its direction has been changed dramatically. As such, we're not ready to share anything about it or any other related work. Please stay tuned for more info on our YT channel and this page.
