click the potion. click upgrades. you need at least one more potion than it says to get the upgrade. you can only buy each upgrade once. play until you reach 10000. then you'll have unlocked all the upgrades. It's meant to be hard. Covid-19 is NOT CAT APPROVED! and what cats approve of we approve of.
Thank you to Cat Corner in Newport News, Virginia for allowing our family to adopt these cute and cuddly kittens (and Mufasa who is a cat who I still classify as a kitten).
