Must have at least 200K Silver, hover on back garden tab, click "Nasty Rat" and grind away all your hard earned Food. I hope its passing a bit of time for you dionysuscool.
Updated the game.
UPDATE 1.04.2020
• Added settings to disable coins (For those who have a weak pc)
• Changed the color of the price at your request (from yellow to purple)
• Replaced “expensive” with “valuable”
For the changes to take effect, start a new game.
production upgrades due to achievements dont appear to effect the income of items purchased after. I.E. Droid tower is +3200 before and after the % bonuses
Thanks!
