thanks for playing :) The bust all eliminates all of one kind. There where more feedbacks about the same confusion, though. I'll see if i change it. :)
I wasn't talking about that kind of confusion, though! When you use the "Bust all", the game screen freezes up for a second, but enemies continue moving: Which means you can still run into one of them.
However I then downloaded the game instead of playing on the browser, and it's working as intended there. So I suspect it might be some bug related to the web release.
