H-games are more fun when hentai is integrated into the adventure, even more fun when it is integrated into the gameplay mechanics directly, and yet even more fun if battlefuck mechanics exist that can turn sexual attacks into potent and useful options. FNAF is a game that by nature is more about avoiding failure, although the faintest breeze of provoking a "bad" moment for a "good" outcome is luring Misty on purpose to exploit her door attack mechanic to waste time. Fun hentai games have playful approaches to make hentai transform from merely a deficit into an occasional asset, though this is harder and rare to do for male protagonists. I think one of the better approaches to an H-game like this one is to have a kind of dual-mode approach where an additional mode should be played and hentai is more prevalent there.
For example, if game story is changed so the danger isn't your character dying but instead getting fired after being caught having sex on the job, your player can optionally take on risk to perv and have sex with the antagonist chasers in a different type of gameplay mission. In this case "safety" can be had by ignoring hentai but if you want to actually have fun the option is there.
This game is a nice playful recreation of FNAF's original goals and mechanics but it underperforms compared to the original in gameplay, which puts it at a disadvantage to other FNAF imitation hentai games on this site that more faithfully recreate difficulty and mechanics from the original, though at a slight loss to hentai offerings. The best way for this game to pull ahead besides the unlockable trinkets instituted in the UE4 version (which really didn't add much motivation) is making hentai more prevalent than merely the artistic display for characters coming to attack you. The game needs to be more interactive.
Although the unfortunate aspect to my suggestion of giving the game a dual-mode nature is any time I suggest this that's subliminally hinting that the core game loop is flawed in a fundamental degree which makes it nearly unrecoverable for having stronger appeal to a wider audience.
