I finished ever17 yesterday and was blown away.
I went in knowing next to nothing, with only a vague understanding that the final route basically made the game.
Base game routes were solid. I ended up enjoying Tsugumi's the most out of everyone. She just clicked.
I really enjoyed the art and soundtrack. The art felt crude at times, but hard a charm to it. The music had the early 2000s vibe and felt ahead of its time for the serious tracks. Well done atmosphere overall.
Reading through the first three days of each route took me some time and energy, but everything past that had me nearly glued to my screen. I enjoyed the plot structure immensely, the way certain scenes matched up and appeared in separate routes. I had chills run down my spine seeing the same scene play out from a different perspective, and things just not adding up. By the end of the second route I had a ton of theories in mind, and loved that the game felt like a puzzle just waiting to be solved.
The experience of it all is something I won't forget. It's one of those games where I think "man, this is why I read visual novels."
I'm eager to find more experiences like it.
