This only exists because the original was really big and I couldn't put more stuff in the original one without it messing itself up. So yeah, arrow keys for the person on the right, wasd for the opponent, uhjk for Onyx's misses (but for END MIX challeng-edd, that controls onyx), space to skip a song, and e for special actions oh yeah, and remix with your oc and a new song if you want to be added.
the original: https://scratch.mit.edu/projects/500424478/ @Crazibot for Onyx and the original version that made sure a part 2 would exist. Krinkels for madness combat Me for making this and the original version (which is a remix and somehow my most popular project (behind my animation edit of @TheTrueColeye's sns remix of blammed and @Scratcher1049 vs. Daddy Dearest)) @cam8089 for his monochrome part Eddsworld, bbpanzu, and @echenninjaforce for Tord's giant robot and @AB7021 for Umbrella Man again
