Someone made a Rock Paper Shotgun game. Well, pistol anyway
Actually none of us are this cool

Polar Star is, basically, rock paper pistol, but with a few dab-handed puzzle twists that make it instantly compelling. You're a saloon dwelling varmint sat at a table with nothing but your six shooter and a glass of whiskey for company, and you're accosted by a chain of ne'er-do-wells. Perhaps there's a bounty on your head. Perhaps it's their whiskey you're drinking. It's not clear, but it seems nefarious. You know what ne'er-do-wells are like.
You have three options: drink, prepare, or shoot. Shoot once successfully - while your opponent is drinking - and you win. But if you shoot and fail, you have to use up your other options before you can shoot again. Prepare counters shoots, and drink counters prepare, preventing your opponent from shooting the next round. But, if your opponent also drinks, you can't shoot next round, and if you both shoot at the same time, you both lose. Or, just you lose really. I assume the game doesn't care.
So, simple enough, but then it throws cards into the mix. One reveals what your opponent is going to do next, one resurrects you both the next time you die, and so on. I had to play the tutorial three times to fully grasp that the game wasn't completely chance-based - it doesn't explain itself perfectly - but I went on a nice journey of realising just how neat Polar Star is during those three attempts. The demo is a bit limited, but it does feature an endless mode with card modifiers unlocked.
The cherry on top is how stylish the game is. Low poly smokiness with neon flourishes and nicotine hues, and some southern-fried electronic OST bangers. You can grab the demo here on Itch or Steam. Or, you could play the real Rock Paper Shotgun game here.
