I think the only complaint I have with Greed Mode after playing it several times is that the button is more of an obnoxious obstacle than anything
The number of times I've pressed it is probably 5% on purpose, 20% by avoiding enemies and accidentally walking into it in the middle of a wave, and 75% standing in the center of the room for more than the half second it takes to pop back up after pressing
this is a kick in the richard alright.
