I am loving the updates to this game! Honestly! It's so much fun!!!
Suggestion: Add speed upgrades to the fan!
I'd like to also suggest some of my own ideas :
An upgrade for the fan that adds a keyboard toggle for turning it on or off. Probably a mid-game upgrade to further automate another step of the whole process.
Consider adding a desk item that prevents selected scratch-offs, or other paperwork, from being blown into the scratch machine. A paper weight or a paper tray?
Consider adding a "subscription" feature from phone guy. Automatically buys a selected type of scratch-off every "x unit of time". Upgradable, so said "x unit of time" decreases for faster automation. (premium subscriber or whatever)
I'd like to see some more consequences for going bankrupt. Bills for your loan. Something to make players juggle some more risk for not being financially responsible. Haven't paid the last 3 bills? You get forced liquidated. Early prestige, and have to start over with fewer points than you'd probably wanted.
