I just finished it. The kindest I can put it is that it's... mediocre. If you're into Tifa, it's worth a look once, but I can't see wanting to come back to it again a second time.
Gameplay can be trivialized by just sprinting and mashing attack to spam the running knee hit animation. This stunlocks all enemies, and even bosses are susceptible to this cheese tactic, which can be good or bad depending on how you want your h-game to be. I also just grinded the alley area for AP to make Tifa tankier, but if you're just going to be abusing the running attack animation, you won't need to grind at all. I didn't need to use the pistol feature of her gauntlets at all to win any encounters, either. Just spam that running attack.
Probably the biggest offense this game commits is that it doesn't unlock the gallery fully when you finish the game, so you'll really have to force a loss to see the different scenes and animations.
Oh, and for anyone looking for the food factory secret entrance, it's
. My dense ass wasted probably three to four in-game days trying to find it.
