Thank you very much for playing! :)
This is still the original gamejam version, but balancing is something I've been messing with a lot recently. It's almost in the state I want for me to start expanding more.
As for the time upgrades, in the current version I'm working on, the first one caps at adding 60 seconds, and the second one caps at 110 seconds, so that the timer will now max out at 3 minutes.
I've done a bit of bug fixing and quality of life stuff as well, like fixing the crash in the 1e300+ range, adding cash/sec and prestige earned this round trackers, and adding a small screen letting you know you ran out of time (to help prevent accidental clicks in the prestige menu).
I hope to get the update out soon but I've noticed I am a lot more picky since I don't have the deadline anymore...
