Why 1 star review? Simple:
1. Without cheating you will always lose the entire game. The game is over when one person reaches 1000 glory. Problem is that you start out at an extreme disadvantage, and they earn about 50-60 glory per day. They also deplete you of your currencies, Energy, Money and Blackmail, often to 0 or close to 0, each day. After each battle you are supposed to hunt down resources, improve your stats, and upgrade your cards... but that requires a ton of Energy, a ton of Money and often Blackmail to do it. Without cheating, you will have lost by day 18-20.
I'm personally nowhere near done, and still can't legitimately beat my opponent in battle so that I earn the Glory for the day, and I'm at day 135. You just do not earn enough Money, Blackmail, or retain the necessary Energy from normal game playing, to actually get progression fast enough, without cheating.
2. The tutorial is a piece of fucking shit. It was designed for a much earlier version of the game, where a lot of the interfaces and controls functioned completely differently. So it isn't representative of the current game in V1.0. A lot of the stuff it teaches you is no longer in the game. It also isn't clear on how to earn new cards, have more than 0 of Money, Energy, or Blackmail after a battle, or how to degrade her Cards.
3. Degrading her cards takes fucking forever. You need to acquire 10 Blackmail, to get to a scene at her house. Each scene lasts a day, so after the encounter, you have to do a battle. Her cards get degraded about every 2-3 scenes. The other problem is that the actual numerical effects decreases very slightly with each degradation and you can't actually invest all your blackmail into one category to reduce a single card type. You have to branch out into 3 others. So, each category has like 12 scenes, and I've spent like 250 Blackmail (some scenes refund the amount), and the most I have in any category is 6 out of 12. And her cards right now, are still retardly overpowered.
4. There are very few sex scenes and you only get them by spending sufficient blackmail. It is always still images. There are no animations. They are high quality images sure, but the amount of effort I went to get them, makes me question if I spent my time well. There is also no cheat to unlock a gallery, like the image here on F95zone seems to imply. Maybe you unlock it after fully completing it but... I've spent 3 hours on it, and only got to a Blowjob picture. Yeah...
Maybe this game was better during development but right now, it is tedious, frustrating, confusing, with so little 18+ content, that no one should play it. It has an interesting card-combat system, pity its broken to hell, and has good writing, but it isn't enough to save this from a dumpster fire. If you removed the porn aspects and actually balanced the gameplay so that someone could win in 150 days, instead of continually lose in 18-20 days, it might be a decent title.
