Ooooh I understand now, thx for rewording it. Thru my playtesting, I haven't really had issues with the opponents killing themselves too often, maybe you just had good(/bad) luck, bc the opponents have different aggresion levels each time they get spawned in and that determines how much they're likely to shoot themselves (of course based on what they think is in the barrel), maybe I'll add a modifier into the settings after the jam so each player could change the opponents behaviour to his liking.
Also I do believe that shooting a blank at the light just removes some points (sometimes all of them), here's how it works:
Imagine this, you have 2.5x mult and 5 points. You shoot the light. Unfortunately it's a blank. You lose 0.1 mult and you lose a point * mult, rounded down. That means you're left with 3 points: 5 - floor(2.4) = 3
We really tried making the game fair, so you could not abuse one action, but nothing's perfect. Thx for the feedback! People like you help me push my games to perfection!
