Oh my fuck I am such a moron.
I think I remembered previous versions of the game having it be bundled into boost and thus did not look as hard as I should have. I swear I scanned every button though! (i clearly did not, I am just incompetant XD )
If it was never bundled into boost then I was just confusing it with some other TBS game...
Thanks for taking the time to respond and sorry for wasting it. Great game, ty for all your work <3
