thank you for the feedback, it's very appreciated!
as for mutually exclusive combinations, i give priority to the one that's strongest, and this can actually be seen with the invincibility power up; technically if you get all of the same number it both fulfills the same number condition, but also the all even/odd condition. but since invincibility is rarer and stronger than any weapon upgrade, the first thing the code actually checks for is if it fulfills the "all dice are the same" combination. otherwise, it starts checking the other combinations, which are weapon related; finally if no combination is matched nothing happens other than the player gaining health equal to the highest rolled dice.
