Wow, this one got me good haha very fun, after you reach the billions i think the progress becomes too slow if thought out as a single session game, like all my upgrades are at around 2-4b i get around 2b/day so it becomes very hard to expand or to buy out rivals, for example a tiny rival in the map rn will cost me 84b which will take me around 42 days to reach. i let it run and then got 100b and bought the thing which supposedly multiplies everything but idk if it's broken or smth it didn't seem to work. Gladly there is the cheats menu in options but even with the 500T i couldn't get to the end, had to use the cheat to see the end of the game.

sorry for the balance issues, but if you hover on the cash amount it will give a tooltip with the breakdown for what each upgrade is producing /day which might help
