So it seams... this is my first game on kongregate and I've just used their scores api, I don't know if I can do something to improve its security. I'll investigate it.
The amount of times your weapon lvled up, looping to spoon counts as +1 as well. Just checked your score, seems fine. It just means you leveled your weapon 115 times. Since there are 11 weapons and 10 grades for all of them, you reach lvl 110 just by reaching all the weapons once. If you looped back to spoon, then you're higher than "weapon rebirth 110".
Scrap needed for upgrades is exponential, you'll hard cap eventually regardless of abusing bugs, using cheat engine or an auto-clicker. =P (This happens because the temporary variable that keeps you in shop isn't saved when you click save, I saw no purpose for it. I guess I was wrong. I'll fix it soon.)
it takes the money from the ore and divides by the amount of time it takes auto click to kill it that gives the g/s and negative means you do less than enough to hurt it with your auto pick and aren't actually losing money
It's a buff, the effect is the same but it uses less gems. You are still better off crafting one gem at a time, the skill is for if you have so many gems that using them all would take too long (or you don't mind using more gems to minimize your risk). Basically each level you use ensures a boost that is ordinarily a bit worse than 1 in 3 chance.
