Interesting concept for an idle game. Overall, not a bad game but there are some annoyances, such as the drop mechanic where destroyed cars lowers the rate of money you make. This is just a plain annoyance more than anything and punishes you for overspending cash.
Another annoyance is the save system. Autosave is nice to have in games but I would prefer if there was an option to save immediately rather than wait for the next 2 minute mark.
There's also a glitch where if you call in a new friend, exit to the main menu before the autosave timer finishes, and log back in, you will retain the new friend and any upgrades you purchase for them before you exited but your cash remains the same as the last save point, effectively refunding your entire purchase without reducing your cash.
