I forgot how to design the microphone Controls for Max: arrow keys. Controls for Bf: WASD press 1 for normal Max, 2 for singing together, 3 for Max to become confident. (it means bf is losing)
I also used 2 sprites of bf for the WASD and arrow keys. you can have them sing a different FNF mod by going on YouTube while syncing the animations. Only if the fatal reactor meltdown song is over.
