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 us on the details as we go. The beginning and the protagonist's first dive into the Lovecraftian horror especially stand out as the most effective bits of the whole VN for me.

Having said that, I do have to admit the rest of the VN, while good, was not as strong as it could have been. While the initial set up is great, the story struggles to justify its large wordcount in the later parts. In particular, the characters feel a bit repetitive and flat after a while: I feel like the story is very effective at establishing their personalities, conflicts, and so on, from the very first scenes, but then the story keeps repeating those same interactions and traits throughout its length without really bringing anything new to the table.

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 about them or their perspectives. It feels like the two characters' entire personalities revolve around the protagonist and the protagonist's reading of them is so accurate there is nothing more 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 that have been noted by other people's comments (sprite positioning and lack of music), I must say the atmosphere was a bit lacking in the scenes taking place on Earth after the horrors were unleashed (this is not helped by all the jokes and casual banter the characters continue to exchange). It was really hard for me to get a sense of whether the characters were supposed to be in danger or not.

Overall, a solid entry and first attempt at a VN, I'm definitely looking forward to reading more by the same dev.
