I broke the game, 13 Exp x2's, 2 rapids, 1 heavy, 1 ricochet, 1 multi, 1 sniper. I don't think all those attachments were why I crashed, I think it was because there was too many coins on the screen and I couldn't collect them all in time.
Awesome, haha. Yeah coins are not well-optimized in this. Should have batch-rendered them. Honestly they probably don't even need to take manual collection but it gave me some extra mechanics to play with attachment wise.
