Welcome each and every one of you to the FNF VS MX Doomsday mod, where MX (Mario) has to battle some new foes, among which we even have Sonic, and we're sure you are going to enjoy each and every one of these songs:
Choose between playing in the story mode or free play mode, and then give your best to reach the end of the songs by playing their notes according to the charts, if you wish to win.
To do it, press arrow keys at the same time as the identical arrow symbols match above BF. Missing to do it too many times in a row leads to loss, so focus not to let that happen. Good luck, enjoy!
This is an open-source game, and you can support the developers here.
How to play?
Use the arrow keys.
