Thanks to all for playing and rating so far!
To jwang19's point, there were definitely some performance issues that became more apparent as you do better in the game (turns out reflowing layout on each leaving audience member callback maybe not sustainable).
I've directly addressed those performance concerns in an update I just pushed, and it definitely is running smoother. Plus, there's a weird Chrome bug(?) that makes the leaving audience members kinda flash a little before disappearing. So that's neat. Safari still hates gigantic spritesheets, so I've noted on the game page that it works best on Chrome/Firefox.
Also found and fixed an issue where you couldn't actually win if you got to 500Million. =) Not surprised no one found that (yet).
