Ok. I have quite a bit to say.
This game is good. I'm gonna be a bit negative in this review, but I need to make it clear that I quite liked the experience here. It's nice, the monsters feel genuine and they're fun to play around with. In that vein, I don't really have anything to complain about 001's route. It's just a good time.
004 tho. Yeah. I have some things to get off my chest, it wasn't good. The route is long, and the ending doesn't really feel as satisfying as it could have been. Allow me to elaborate: the buildup is weird. It's long, and the knight is a bit *too* trigger happy. This isn't really a problem on it's own, but coming off from the sweet and short 001 it is quite jarring just how much harder 004 is. This isn't a big problem on it's own, but there is also the payoff of all that buildup, where it is revealed that you are a reincarnation (I think?) of the knight's master. The issue? What was the point of everything else if you were just the master all along.
Your choices didn't really matter here up to this point, past the ending it felt like you as a player is just thrown from one scene into the other until the game decides that you have won the lottery and you're actually his master. In a game that markets itself with "from blackmailing to flirting anything is fair game" you have surprisingly little say on how to deal with him. It would be better if you could convince him through helping him process the death of his master, or through a newfound passion for cooking, or - here's an idea - instead of straight up killing you when you make a perfect armor maybe it would send you down another route where you gaslight him into thinking you're the master when you're really not. It would be better if the sword was scrapped altogether, just *something* to make you feel like you did something, that makes you feel like, you know, an actual mediator. For now, the lingering aftertaste that the chapter leaves in your mouth is that you got lucky, and luck doesn't really feel good.
Both monsters so far have been solved mostly through who you are rather than something you do. For 001 I can forgive it, since he doesn't really overstay his welcome and it's playing into a very specific fantasy, but it should be a one off thing. Unless there is another route for the knight I'm not aware (and if there is, please tell me), it being solved the same way makes me worried for the game's future and the direction it is going. I bring this up because there is a lot of potential here, again this is not a bad game by any means. But it can be improved. I hope you take this the best way possible, but 004 is frustrating when it didn't really need to be.
Uhhh yeah. Best of luck.
