Probably the best summary of this game is these four words: Was it worth it?
That's the huge, huge thing that will determine your enjoyment of this game. When you die probably close to 20-30 times in a single encounter, several times when the last enemy left- and, sometimes, a single extremely powerful enemy- is basically hobbling on their patellas because everything below that has been turned into a thick, chunky mash, was it worth it when you finally win, 2 HP left but knowing that you'll wind up in the same situation again later?
Was it worth it, basically knowing that most of your choices in this game, no spoiler, involve ♥♥♥♥ing someone somewhere over in the worst and most permanent ways imaginable? Was it worth it? To be honest, I can't speak for many other people, but to me, I think it was.
The game might be unfair, yes, brutally so. But eventually you get into the mindset of "losing is actually kinda fun", you start trying out new things to see what works instead of getting ♥♥♥♥ed because you had to restart again. This is the kind of game where you're honestly expected to do that, and it's designed so that there's enough variety in how things work, and when, that even as restrictive as it sometimes feels I wind up WANTING to try out new things to see what works.
It's the kind of game that, sure, literally everyone in it I've seen so far is about as sympathetic as a ♥♥♥♥♥♥ cockroach with swastikas engraved on it's brains, including the player character, but the lore and writing are good enough that, by God, I'm actually keen on playing it to the end- once it's finished, of course- just because I'm interested to see what's gonna happen.
This is ultimately where "Is it worth it" really comes into play. It's a brutal, often frustrating game. If you ♥♥♥♥ up, you're going to die, whether it's in combat or in how you allocated points for story encounters, and the game seems about as non-chalant about it as a US president swatting a fly on TV. This is not Dark Souls, tired as that comparison is, because even that game seemed to wanna give you a chance at times. But if a game where ♥♥♥♥, EVENTUALLY, comes together, where you EVENTUALLY get it and EVENTUALLY you make it through sounds appealing, I'd say give it a shot. At least the demo, since, you know, there's a demo. For once with a game.
♥♥♥♥, that's enough reason for me to wanna give it a recommendation.
