A quick little update to a slightly broken game

Well, it wasn't quite working it seems...

After some feedback on how things feel, as well as some discussion of some known bugs, I've re-visited this project for a bit to fix things up!

Balls should now have the correct value, after token upgrades are bought, and save files should be a bit more stable.

I've also LOWERED the scaling of the cost of tokens, so they should be slightly easier to obtain in larger amounts now :)
