Look, this game starts REALLY strong. I loved Omar and specially Evan. A really nice duo. And the first scene with Omar and specially the threesome scene are GREAT. Great beggining. But the entire vibe of the game shifts, in my opinion to the worse, with the Leon commander. Yes, yes, he´s in the cover art. But I do think it kinda ruins the mood for the MC to immediatly declare undying love for him (the following day to the threesome funnily enough). Yes yes artistic vision, but I still think it would have been better if they had allowed us to pick between the three of them.

Prior to starting this, the game had seemed fairly auspicious given how 'eye-catching' the visuals and layout appeared despite it not being too radically different from the general Ren'Py VN setup. I will commend the artist for their drawing style and it is the game's major saving grace. But where it underperformed for me was the lack of depth in the plot outside of the filler humor as well as the lack of personal autonomy in choices. I will admit that I had gotten a few genuine laughs out of the playful banter. I did enjoy the way that the sense of fraternity was established even if others could consider it cheesy--there's still merit in it. But otherwise, I feel as if the plot had missed out on the biggest opportunity on developing the war against the Pronithians and any thought-provoking lore as a result. There was an introductory attempt at it albeit I could be expecting too much from an 18+ BL visual novel. Personally, I find there to be a lasting effect when a BL visual novel game finds a way to stand out in the more serious part of the plot while still incorporating romance elements in a way that they work synergistically rather than one detracting from the other. The lack…

This game was short but overall very enjoyable to play the vibes this game just immediately puts you in the atmosphere the game is trying to portray. I also thought Leon x Alexis were really cute as a couple and kind of glad that the MC pretty much had a canon partner because most BL visual novels don't do that. My only real gripe with the game is the last chapter of the game has a strong tonal whiplash from the rest of the game that is kind of glaring and then the game just ends after it traumatizes the characters. I would still recommend this game for the art and characters alone as I enjoyed getting to know them and bang each other lol (all the Leon and Alexis sex scenes plus their threesome scene with Evan chefs kiss). Overall, I would definitely recommend this game for the BL lovers but not the people who are expecting a thorough exploration into the Science Fiction Genre.

Surprisingly, it turned out to be a great visual novel. The concept, the setting, the characters, the NSFW - just perfect. Not the plot, though. It was decent. It was more of an exploration of each sexual tension and desire. It is not bad at all in the context of playing the game without the huge intention of exploring the lore of the universe, and even if you are really interested in the story, this game has a great way of changing your perception, so you adapt really fast Don't get me wrong, but given the circumstances, the game's flow is perfect. Art style is amazing. Thank you for avoiding AI. Interestingly, the characters' bonds turned out the way I wanted them to. It was funny to see how my interesting idea of the course of events came into action right away, when I thought that this wouldn't be in it. Outside this game, I wouldn't have this idea, but the chemistry between the characters was radiant and just felt right

I've been waiting for this title to come out for months and I can confidently say I'm not disappointed. While the dialogue and scenarios at times can be a little lack luster and borderline hard to watch, I think the developer did a great job fleshing out the sci-fi themed story and world which reminds me of one of my favorite BL titles on the platform which is The Symbiant! The characters are all endearing and charming in their own way despite some minor tweaks that could be improved upon on the way their written, specifically in the romance aspect. A lot of it feels rushed and I don't fault the developer cause I'm sure it's quite a lot of work to produce a game at this scale and write over 100K+ words and do all the programming for that, but it leaves you wanting a lot more. I personally enjoyed the side story between Evan & Ollie and thought it was super sweet especially tied in with the story's plot and Evan's backstory that gets revealed end game. All of the CG's, backgrounds, and character designs are flawless and gorgeously drawn! It's always a pleasure to see more games with beautiful artwork and see more sci-fi and futuristic/apocalyptic themed games in contrast to some o…

I'm glad I supported this visual novel's Kickstarter and was very excited to play it as soon as it was released. The writing is more than adequate and very captivating — detailed enough for me to imagine everything that is happening in my mind but also lively and stimulating enough to keep me excited and anticipating what would happen next. It is also humorous at times as well and I enjoyed reading it immensely. The story is a bit on the shorter side, which is fine, though it left me wanting more after finishing it. The visuals are seriously high quality, vivid, and very highly detailed. I felt like I was right there along with the characters and felt the ambience of every scene, the cosmic dread of being deep in space. I also really enjoyed the sleek, sexy, ultra-modern outfits the characters wear. Of course, the H-scenes are very hot, explicit, and enjoyable. If you like racy, X-rated, hardcore sex scenes then you definitely won't be disappointed. Also be prepared to get the feels from the music, from cinematic and emotional, to light-hearted and uplifting, to existential and meditative. Overall, I was impressed with the quality of the visual novel and can't wait to see what Vinc…
