Social XP doesnt do anything. Also, Strain doesnt do anything. You can start out the game busking and keep going to your hearts content while making bank. First your food diminishes to zero, then your strain starts to increase, but when it gets to max, just nothing happens.
Otherwise seems like a fun little incremental game. Not sure about the tags though since I didnt find a lot of adult or nsfw content to be unlocked, or atleast couldnt figure out what route to unlock them from. With the money from the infinite busking I could unlock everything available, but there wasnt a 'dating' option or something akin to that which I was kinda expecting.
