OKAY LOL- SO BASICALLY WHAT https://www.trueachievements.com/a362432/see-you-space-boyfriend-achievement SAYS, BUT THERES SOME STUFF I DID TO MAKE IT EASIER
SO FIRST I GOT TO LEVEL 15, THATS OPTIONAL BUT IT PROBABLY HELPS, AND KEEP EVERYONE HAPPY. YOU CAN USE SPARKLERS BUT I RECOMMEND AUBREY’S PEP TALK BC ITS FREE (OTHER THAN JUICE). USE IT ON KEL, THEN OMORI, THEN AUBREY, THEN HERO. THIS WILL TAKE MULTIPLE TURNS, BUT ON THE FIRST TURN, KEL SHOULD USE ANNOY ON SPACEBOY, THEN OMORI SHOULD USE MOCK. MAKE SURE NOBODY GETS SAD, AND KEEP THEM HAPPY. MAKE SURE TO USE FOLLOW-UP ATTACKS OFTEN, BUT YOU WONT ALWAYS BE ABLE TO, SO I RECOMMEND OMORI’S STAB, AND KEL’S FLEX (THEN USE A REGULAR ATTACK AFTER HE FLEXES).
