Gameplay grinding + farming gets old and boring fast. Same thing for the spicy scenes mini-game - can't enjoy it when you're toggling the buttons to try to level your bunker girls. There's also the problem of the guys out-leveling and leading the girls 3 to 1 in levels. They'll be level 15ish while the two guys are already 70+. Flawed gameplay flow and design.

The story and art is ok; but the combat is bizarre. The game is both grindy and plays itself. I was able to cook dinner, dry clothes, clean the bathroom, and sweep the floor - all while "playing" this game. I was in effect micro-managing an auto-battler every 60 seconds or so, for hours. The premise was interesting and I had initially intended to mildly recommend it on discount; but the game loop is that insane flavour of hentai grind; and gets geometrically worse the more you play. Also: The erotic mini-game is a chore with no cues of which way your partner wants the cadence to change - and why is the protagonist's bar [i]also[/i] non-linear? It serves no purpose and makes it much harder to tune your partner's cadence. I actually hope this game was coded by AI. As the alternative is that a human considered this to be enjoyable game play.

The gameplay is fairly simplistic. Basically, you level up by doing it with heroines and then go to a stage to kill zombies and get ressources that you use to power up weapons. A bit more involved than a visual novel but not by much. Art is good.

Actually quite fun and has some funny dialog, not to mention few yet very hot sex scenes.

Simple game mechanics, but very good at keeping my attention. The story is absurd, but it acknowledges that within itself and is still greatly entertaining. The story is actually the best part of the game. Really enjoyed this one, and I'd like to see more games like this in the future with some expanded ideas. If I could change one thing, I would like to see more player involvement in the actual combat, but otherwise a great game.

Weak recommend. The art is good, even if it's AI. The game itself is engaging enough, but grindy. The two biggest demerits in my opinion are the grindiness of later levels as well as a levelling system that, to me, seems fundamentally broken. It also overall lacks content in terms of CGs and scenes. The later levels are simply put, way too long. I found myself tabbing out while they played in the background once I was confident of my setup. There isn't much variety in monster types, and despite what you may expect, the most dangerous ones are, in my experience, the runners. Runners are one of the most basic enemy types, but they sometimes come in such numbers that your characters will take damage regardless, and the way level ups work make at least 2 of the 4 characters you can deploy each run very fragile. I recommend upgrading your weapons early if you can, and having a variety of weapon types. Shotguns do a lot of damage to big targets, but struggle against lots of weak enemies (whether or not that makes any sense) As far as the levelling system, after each raid, you can have a sex scene with any of the unlocked female cast. In concept, you are supposed to make her orgasm …
