It's a battle fuck RPG for the ages. For those not in the know, battle fuck RPG refers to a game where battle system involves sex, usually with the player trying to outlast the opponent. Combine this simple yet effective system with gorgeous artwork and smooth Live2D animations and you've got a recipe for success, all that's left is the execution.
What makes this game unique is the stance system. At the start of each fight, you enter one of 3 stances which then determines your move set. Which stance is available to you depends on your dialogue choices as well as equipment that you can unlock through the game's skill tree system. Each stance has its own unique playstyle, from more defensive approaches to all out glass canon for those who like to live on the edge. You can either try and adopt multiple stances or lean into the playstyle that suits you best.
Combat is all about managing a bunch of gauges and counters. Enemy attacks will raise your EP, which when filled will deplete a portion of your LP. Lose all your LP and it's game over. In the meantime you're trying your best to fill the opponent's mood in order to defeat them. By chaining together a bunch of skills, you can set up combos for big damage. Fights can be pretty challenging, especially on hard mode, but the system is well worth learning and creates for a satisfying experience worthy of mainstream RPGs.
Another standout system is how progression is made. Each time you defeat a boss, you must sacrifice the current player character. Afterward, you pick a new character to carry on the legacy and press onward. Like in the SaGa games, your heroes will inherit the cumulative abilities of their previous incarnations. While defeating a boss will force a player death, keep in mind that losing any fights will also require you to choose a new hero to carry on while your progress is effectively stalled. With a limited number of heroes in the game, you can't just throw away your lives willy nilly or else you can force a game over.
Level selection is like Mega Man where you're free to tackle each stage in any order you like. While there are characters associated with each of the bosses, you don't have to match them to each boss if you don't want to. Also the overall difficulty is increased depending on how many bosses you've beaten, as determined by the dream level thermometer at the base.
If you do end up losing all your guys, then you're always free to continue with New Game+ to make the next run easier. You can approach this game as casually or as hardcore as you'd like, but I think the game systems are refined enough to warrant trying your best at a hard mode run. With legitimately engaging gameplay systems and gorgeous artwork, this game pretty much perfection and an amazing way to send off the year.
