This turned into a wall of text (sorry!) I'll post a TLDR at the end.
This game should come with a warning. It's very good. I played for about 8 hours barely stopping until had to stop because I was having an anxiety attack both from how intense the game was getting but also because of how little I'd taken care of my self. I came back to it the next day fresh and determined to make it to the end.
What an experience. I was enjoying the game immediately but was only taking it half seriously, The main character would react and I joked to myself about the dirty thing I would have said instead or the like but the game took itself seriously from the start. It takes time to set up the relationship between the MC and Amicus and gradually just as the story progressed Ilike the MC grew deep feelings for the characters in this game. It tugged my heartstrings and evoked genuine feelings of joy, despair, fulfillment and agony. It was emotional roller coaster and I was hanging on for dear life.
The art and sound were really well done. I loved the art of Amicus. He has plenty of varied expressions to help set the scene, though all characters did to be fair and there are occasional full scene artworks that are stunning.
There a few sci-fi tropes sure but they don't detract from experience and world building the game sets up. There was only one twist that came out of the blue, that felt like it only existed to create forced drama and it does serve to progress the plot well and does get explained fairly satisfactorily but at the time it was a little jarring. I did feel mostly the same way as the MC did, hurt and betrayed but I was also aware of how forced the whole situation was, so I guess part of the hurt was that the developers had stooped to that level for an emotional reaction. This is only a minor nitpick though as the whole experience was just incredible, I've read compelling VNs before but this one just steals the show.
I guess it's only to be expected, I really enjoyed Blackgate back in the day and this is from the team that formed to take on the side project to Blackgate, Echo. There's a reason why blackgate has lost momentum and basically died yet this game has far surpassed it. I haven't even tried Echo since some of the earliest builds but after playing this I will have to, though not for a while, I need time to process and sort out my head after this game.
If you are on this page looking at this game then just simply download it and play it. It's free, you would only be doing yourself a disservice by not giving it a go.
TLDR - It's an amazing, emotional game and you really should play it.
