I don't think you can "cheat" at a clicker/experience game.

I wouldn't sweat it.

Even those javascript hacks posted on the page here are fair game.

I finished the game. I don't begrudge anyone for making it go faster.

I think this is considered smart thinking (from my point of view).

Spam DVD logo upgrades as fast as you can. Open your browser as big as it will go. When the DVD logo gets close to the top, start shrinking the browser slowly. I think the DVD positioning is calculated from the bottom of the page, there's a bug where the logo(s) will get stuck near the top as you shrink the page and will constantly re-register a bounce multiple times per second. Eventually all the logos you buy will get clumped at the top, and you can get 1MM Stimulation per "bounce".
