alright folks i got a stupid fangame idea (big spoiler time):
i haven't played this game in a long time so expect some inaccuracies. after one of the two worst endings where soul nukes the joyful part of soma, heart survives using 50 tons and 23 grams of plot armor, and has to bring joy back to soma. the world is progressing technologically as quickly as ever, and soma is getting extremely powerful due to this, but this is offset by the fact that simply nobody is happy. so, heart needs to bring joy to soma (and somehow, JUST SOMEHOW, knock some sense into soul) with that acorn dude in the first area, who has now become a sprout, and that box guy from the second area who has decided to give up his job.
