Playing on PC, when the 'cash out' sound plays on my system, I swear it's clipping. Or maybe the same sample is being played twice one on top of the other? Either way it's abrasive and loud. I am listening through a PreSonus AudioBox 22SL, so potentially old drivers, but no other audio in the game sounds like that.
Also, I feel that Flower Pot and Smear should work together, or maybe that's just me wanting to have found a cool combo. Either way, maybe the text could be more clear? It sounds like they should, at least the way I read them now.
