Skills Points

I have a suggestion to add skill points because later the lvl becomes redundant when you unlock scar

armor (humans): [0/20] - (increases Kevlar) ; 1sp = 5 kevlar ; 20sp = 100 kevlar;

critic (humans : [0/16] (increases criticism) ; 1sp = 2% crit ; 16sp = 32% crit;

damage (humans): [0/30] (increases damage) ; 1sp = 1% dmg ; 30sp = 30% dmg;

health (zombie): [0/30] (increases health) ; 1sp = 100 hp ; 30sp = 3k hp ;

penetration (zombies): [0/60] (skipping armor) ; 1sp = 0.5% skipping armor ; 60sp = 30% skipping armor;

durability (zombies): [0/10] (reduces damage) ; 1sp = 2% reduces dmg ; 10sp = 20% reduces dmg;

bank (all) : [0/10] (increases the amount of dollars) ; 1sp = 10k ; 10sp = 100k

1lvl = 1skill points
