(Only one girl out of the four, but a redblooded man like myself can dream for character customization or more characters to pick from and swap out in the future, I guess.)
(Kind of a personal nitpick, but I wish lewd games were all male, all female, or roughly 50/50. It's just confusing when all-male or all-female games just slap in one girl or one guy.)

Anyway, the game is RNG based, pick your target (including yourself), pray to RNGesus that they inflate, yadda yadda, you've probably played these things before.
No tools or strategy implemented yet, so it's just the RNG and nothing else.
Normally that'd be a problem, but if you're here for the girl you can just single her out and she'll probably max out pretty quick, plus the NPCs like to target themselves sometimes, and all this adds up to the odds stacking in your favor.

RNG-heavy games piss me off to no end and I tend to rate them low on Itch or elsewhere, but it's not that bad here, and the game's score gets a little bump from the music, heh. As long as the dev continues to update the game and not abandon it like the other 9999 Russian Roulette games/clones, this should be a fun one to keep track of.
