This standalone DLC takes you through two pretty much standalone routes. Yes a lot of standalone stuff here ≖‿≖. Having already played the first game, I can only add that I have enjoyed the expanded lore and stories about Danya and Brahve, and yes, the lesbian snake lady.

At the start, you can choose between the Cayama route or the Odaria route. I began with the Odaria route and saved the Cayama route for last, but honestly, I wish I’d done it the other way around. Because, goddang, the Cayama route is heart-wrenching, full of heavy emotions and the pain of breaking up. "It was selfish of me to reach out to you. I just.. wanted to see you so much..". -dies inside-. "I made things worse by reaching out to you." -dead- This ending oh my god, absolutely devastating, my heart aahhhh (๑˃̣̣̣̣̣̣︿˂̣̣̣̣̣̣๑).

The Odaria route is much lighter and sweeter, with adorable and steamy moments, almost like a honeymoon phase. Not too much 'deep' story here, but just cute 'n sweet bite sized dates. It did it's job well, left me just wanting more. Again the voice-acting is stellar, great art, and the overall vibe is both emotional and spicy in all the right ways. I love my two space boys and hope to see more of them someday!

Recommended! While you don’t need to play the first game to enjoy this standalone DLC, I do think the original is stronger overall. If you're on the fence about where to start, I'd suggest picking up the first game first!

Okay but seriously I kind of wanted another Oatith scene where he possesses Brahve to steal Danya for himself. But alas no yandere plant alien for me. ;-;

But in all seriousness it is very short and fast paced but definitely worth the purchase if you loved the first game. You can have a cute fluffy honeymoon-like vacation on Odaria where Danya and Brahve are a happy couple. Or you can have a dramatic time on Cayama where after breaking up Brahve shows up two years later wanting to rekindle the relationship. I admit Brahve becomes more punchable than before in the Cayama story but I kind of prefer that storyline actually if I had to choose between them. (Brahve kind of pissed me off in general during the original game so maybe I am just biased lol)

I AM ROTTEN so I would've preferred it if the story and characters were more toxic, deranged and mentally unhealthy (specially in the Cayama tale, I was picturing many bittersweet scenarios already with that gorgeous, addicted, broken and slutty Brahve but turns out it had a happy ending instead.. shucks), because that's what I live for but really, The Symbiant is so good I can't bring myself to talk poorly about it. I love it. I think this game is a very good example of a surprisingly good balance between kinky and healthy!! Like, I hate "The healthy stuff™" because it feels cringy trying to sound always too morally correct and sanitize fiction, but The Symbiant does it in a way that doesn't seem unnatural, tryhard or far-fetched.
I'M SAYING THIS TO CONVINCE ROTTEN FELLAS LIKE MYSELF TO GO AND PLAY IT!! And I'm congratulating the author because I know it's super challenging achieving that balance.
Someone here in the review section said it was bad that the writer pointed out Brahve was not gay but omnisexual, and that male odarians can lactate but I think it was wonderful, and to me it only added even more admiration points for Brahve... LIKE come on, omnisexual pride!!! WE EXIST!!
In the end of the day, the bad reviews are about people's tastes and not about how good the game is! That's why, albeit my personal preference being TWISTED STUFF I gave this game a good feedback! You have to see past your personal tastes!
The only cons are: I wish we could've seen other alien species mentioned as NPCs and Chohra's house too, and I felt like the sex scenes were shorter in ReUnion than they were in the original game, also. I miss listening to Brahve's moans. His voice is such a delight...... Brahve................. Brahveee......
