Have been looking forward to this game since around 2016, I think? I finally got it and finished it last night. Just throwing my two cents,
Despite being overexposed to the game (2016 ffs its 8 years later!), some of the unseen content that is in the final game was pretty cool! Mostly to the very, very end of the game. All in all, for an H game - it's quite fun. Same impression I had so many years ago. Nice music, fun characters, and a cute sidescroller/platformer.
If anyone enjoyed their time with the Fire/Electric demos across the years and just wanted to finish the game - it's definitely more of that, in a good way. Some of the ice level/end level puzzles were pretty fun too, adding an element that isn't in those demos. Also, the extra dialogue options accessed through the personality traits and Faye's rep adds some fun replayability to the game!
But,
I was really upset by some of the later parts of the game completely missing any sort of dialogue/voice though. I think the game could have done with less stat-check NPCs or stat-related items if it could have led to the game coming out with a bit more polish? I'm not really sure how dev time gets split apart, but releasing a game where the characters talk non-stop for small world-building but have no lines for more crucial world-building/boss scenes/etc. is a strange decision. (Swamp zone boss fight is just completely missing dialogue with Vie regarding the fragments. Also, a lot of the later golden databanks have no audio? Some that I genuinely think had audio in the demos? Strange.)
With the amount of discoverable sex scenes (dialogue with NPCs and agree to have sex with them or finding Faye tangled with someone), I think it's actually insane that they aren't in the gallery! Especially since the gallery needs you to unlock it through achievements, it feels barebones for a game that actively wants you to find these and maybe even replay the game for them.
Way back when, I was really looking forward to a Faye spin-off but I feel like another game coming out of the team must not be in the books considering how many setbacks FF had in its development. Maybe a Faye mode in the future? Maybe nothing ever? Maybe a different type of H game? Who knows.
Despite being a fun H-game with a lot of effort and budget put into it, it left me wanting more, and that's a shame. I feel like it might be a case of struggling to keep that consistency across the game.
