Remaster imminent Double-click flag so that the music syncs! You can replace characters by going into their costumes and replacing the poses with your characters' poses. You can also change some of the animation code if you want it to look different. I considered using 3.0 sonic, but I've got something big planned for him so I'll save him for now (also I know saying this counterdicts what I said in challenge-exe, but another factor here is the original video used this sonic.)
Thanks to YouTube for the cover, and Funkipidia for Mario, Sonic.exe, and the mansion. Yes this has less effort put into it than others, I will fix that in the future. Update log: 1.0: release 1.1: fixed mario's up/down pose (thanks @FNAF-Fan135) and added a thumbnail
