Come for the porn and story (if you're into that), stay for the gameplay.
Revenge Game: Cumshot or Death speaks for it's own title wherein you duel your high school bullies in a hellish game of sexual teasing, where victory is only achieved by avoiding a stain on your trousers. Taunt, gaze at their privates, moan, even spit on them in an attempt to get them upset and stall the time limit of 4 minutes. Win the battle and claim each of the girl's four hearts in this corrupted game and you'll have the fate of their lives in your hands, and your own.
The gameplay is incredibly balanced, with upgrades to your skill tree and moveset expensive enough for the game's currency, revenge points, to be highly sought after. The game rewards inaction by letting the girl's complete their own objectives to defeat you reward you with more revenge points. This will be difficult to take advantage of when you start to unlock more options in your every-turn operations. Upgrades on the skill tree are also highly rewarding, giving you new avenues to thwart the girl's plans and give you extra turns in the cumshot battles. While the game might be difficult, figuring it out and learning to break the game is highly addiciting. For those who enjoy trying to optimize the use of limited resources, and completing limited turn playthroughs, this is a great game for you.
I will leave the evaluation of the story up to you. The heavy themes, bizarre setting, contrived sexual action, and magical elements may turn you off, but the game should be applauded for making some truly deplorable human beings, and an MC that can't be rooted for, leading to an ending where it feels like no one is a true winner. This is definitely refreshing compared to it's contemporaries.
The game's sexual content is fairly healthy. Each girl has a handful of CGs modified with Live2D to add some flavour, and voice acting to supplement the dialogue. For those who enjoy being the masochist, the early part of the game will be to your liking, but you may find the ending portion to be lacking. The opposite, for those on the other end of the spectrum. I think the art leans in between "well done" and "serviceable", which attractive designs but for more trained eyes then mine, probably reprehensible.
Even if the art doesn't immediately draw you, this game has enough going for it that it is worth the day's worth of time it will take to get through a full game. This is absolutely a game worth trying out, you won't regret it.
