First Slime you fight is value 1, then 2, then 3 Etc. This effects Stats and Loot. 10 skipped slime value means the First you fight is 11 then 12 and so on.
I loved IdleFighter too, but the code was all made while I was learning, so it is very sloppy and hard to work with. This game will implement a lot of the themes with a less cluttered and bugged interface. I will not remove the previous game though so feel free to continue to play it :)
