Before I begin: while I did finish the game, this review will focus on overall game play and gay parts of content(both m/m and f/f). If you don't like that stuff, feel free to skip this review.
Gameplay overall:
The devs did great job with this love letter to Sweet Home on NES. As someone who played that title, I found many nice nods and references to it, in both gameplay and atmosphere. Seriously, don't turn the music and sfx off and play with your headphones on, you won't regret this. When it comes to h-scenes and other 18+ content, the game does a good job again. But just like old games you'll probably need a guide to get exactly what you want out of this game. I also can understand people who got frustrated and opted to simply use save file instead. The game can be very confusing and frustrating at points(especially near the end of the game) and the overall game balance feels off. In conclusion, don't feel bad for giving up on this game, it was made with a specific audience in mind after all.
Gay stuff:
If I had to describe it as short as possible: denial land. Everyone is TOTALLY straight until they aren't. In case of girls, they go "ehehe, we're both girls, it's fine to grope each other and passionatly make out~" and the guys go "ewwwww, I'M NOT GAY, it's this mansion's influence, I SWEAR". But after finally getting past that, the scenes are surprisingly romantic and even wholesome(unless you're cheating on somebody or getting a bad ending). There are plenty of different scenes for every same sex couple(even the ones that don't feature MC). Everyone is bi and a switch, so no sex scene feel stale or repetitive. Another nice touch are epilogues for each potential couple, they range from sweet to funny af; Yachika and Rikana's in particular gave me a good chuckle. Speaking of Yachika, I honestly think she should've been a lesbian - her chemistry with girls is somuch more interesting than any of the boys! But maybe it's just me...
I should also mention Harem stuff: m/m/m part of it was simply delightful. Funny, sexy and memorable. For the girls, I wish there were an alternative scenario with just three of them without Homura involved. But alas.
In the end, it's just nice to see gay content not being a simple afterthought, but a fully developed part of the game, on par with hetero side. I wish more devs included same-sex content with that much thought put into it. If you're such a dev, please take this game as a good example of how to blend different types of content without one of them feeling lesser than another!
Tl;dr if you don't mind a somewhat outdated gameplay and can get past "I'M VERY STRAIGHT, NO HOMO" part, I highly recommend this title. It's somewhat of a must play for the fans of horror too!
A strong 8/10.
