Mouse-only. Gotta click 'em all. Or you can try. In fact, I'd like to see you do that, really. That'd be entertaining, to be honest. One moment while I get some popcorn...
Need notes and credits? Notes: CLICK THAT BUTTON. Credits: 40% me, 10% me, 10% time that I have nothing to do, and 40% that red button in the screen that you're failing to click. Also, if you have any more memes that you think could go well with button-avoidance, just post. Got a bug? Post please. Clicked the button? Heck with it, go ahead and post :)
