Ok I don't mind that skill upgrade go past 7, but I had 1 not come up at all and beat the game as that character.
really should set once they get to say 8 or 9 they don't come up as often or max out at 9 or 10.
Also would like to see stats area to see what you killed
I mean i got to 30k kill and one skil barley comes up is at level 3 Maybe have a feature after you beat the game you can roll some stats over to another character.
