okay so... hacknet has a silly little cookieclicker minigame you can find as ... well, as part of one of the missions in it. you CAN play it. it lets you play it.

...turns out you can goddamn break it too without even having to hack anything.

I bought so many of the final upgrade that it overflowed and actually started REDUCING my points. I am now in... massive negative figures and can't even click the free "upgrade" XD
