So i am making an in-game currency and its like
I have set that after a bit score a bit of currency would increase
like If score is >= 2 then currency+= 10; and so on for more different scores. but i am having an problem as if i the score is less than the one in script like if its less than 2 then the currency resets to 0, idk why.
i am using playerprefs, ik its not safe and all that but for now im just going to use this.

and if the currency lets say is 50 and the next time you play and get the score which couldnt get you more than 50 coins, than also it resets back to the currency that is set into that particular score you earned at that moment
