Love the concept and the dripping of storyline throughout. I may have missed the part where this is addressed, but it wasn't clear why the doctor had amnesia at the beginning. I also felt like the game was leading up to a big interaction with EVA throughout, and then when I got to the ending it didn't give me much chance to really interact with her. But I loved the twist, and the self-contained nature of the game. I'd love to see an expanded version!
I actually recorded my playthrough. If you want to see my impressions as I played, you can see it below (timestamp for your game in the description). Hope that can be useful!
