[BALANCE] Unnatural Growth Incremental

It's very weird, it's still new, it still needs improvement, it still needs more contents, a lot more. But, if you guys want to support it, we all welcome and thank you for your supports!
Unnaturally, game is focus all into Growth, everything all in the end having the end goal of making Growth go up!
