The new pause feature when you move your mouse offscreen still needs a bit of tweaking, it's really annoying if I accidently move my mouse off the screen trying to dodge thousands of bullets coming at me and the game pauses halfway through it. It would be better if the mouse of moved off the screen for a certain period of time before it pauses.
I found a money bug. I beat the first race with the duck that gives you $50 for winning. Then I went into the tournament room, came out again and I had a free $50 added. And it would do that every time I went in there.
To fix the lag: right click in the game, press 'settings', then go to 'storage' (the middle tab), and put the slider to "unlimited".
