@munch: That sucks. Never seen that before, except sometimes Windows (Vista or Win7) dims out a window if it thinks the window (task) is unresponsive. It partially bases this on CPU consumed and ability to preempt the threads running in that task.
Now why I came here. Have you ever sometimes bombed a few waves ahead and then ran out of gems to bomb with and accidentally clicked in a wave stone down the list, thus releasing a whole lot of angered waves prematurely? Well, today I was messing around in an endurance game and I noticed that if I click on one of the top wave stones, then you can effectively stop all the waves from being released.
For instance, if you have clicked on wave 25 and released waves 16, 17 thru 25, then if you are quick and click on wave 16, that will be the last wave released.
ALso, I was getting bored and wanted to see how high monster HP could go in an endurance game. On level #69, wave 305, the giant monster HP was 1.42338529258655e+21. I don't even know what that number is.
I'm still slugging my way through playing every mode on every level. I'm now at >270M XP and I think about lvl 1600 wizard.
It's getting mightly boring, I can barely bring myself to play more than 2 games a day.
