The beginning of the story gripped me pretty solidly! I like the writing and I like how story managed to avoid overwhelming exposition by starting the story medias res and filling in the details as you go. I feel the beginning and the protagonist's first dive into the Lovecraftian horror stand out as the most effective bits of the whole VN.
I do have to say though that the rest of the VN, while good, was not as strong as it could have been. I feel like, while the initial set up is great, the story struggles to justify its large wordcount in the later parts. In particolar, the characters feel a bit repetitive and flat after a while: I feel like the story is very effective at establishing their personality, conflicts, and so on, from the very first scenes, but then the story keeps repeating those same interactions and traits throughout without really bringing any kind of novelty about them?
I feel like this is very clear in particular in the two scene where the POV switches. I feel like despite being in these characters' heads, we don't really learn anything new? It kind of makes it feel like the two characters entire personality revolves around the protagonist and the protagonist's reading of them is so accurate there is nothing to add.
In terms of presentation, again the Lovecraftian nightmarish scene stands out as especially well executed, and the music/sound design (when it's present) it's pretty on point. However, there are plenty of points where the presentation is a bit plain: aside from the obvious points (sprite positioning and lack of music), I must say that I really felt that the atmosphere was a bit lacking in the scenes taking place on Earth after the horrors have been unleashed (this is not helped by all the jokes and casual banter the characters continue to exchange, it was really hard for me to tell sometimes if I was supposed to feel like the characters were in danger or not).
Overall, a pretty solid entry and first attempt at a VN, I'm definitely looking forward to reading more.
