I was looking forward to this, until I saw that another poor developer has decided to be clever and not only severely limit the renpy options, but cut off access to the options all together while the visual novel is in session. This is a terrible idea and practically ruined the whole experience. I really don't understand why anyone would do this, but an alarming percentage of developers have been cutting off the very user friendly options which make renpy a good visual novel engine. So I have to say, I did not enjoy the clickclickclickclickclickclick fest this was because my read speed was four times faster than the default scroll. On a related note, the TV static was cool at first, but after the 30th one, they were getting too long and I was skipping over them. From a design standpoint, I don't like developers who try to take control away from the reader. If the reader wants to skim, the reader skims, one way or another.
I found the presentation to be atmospheric, but the novelty was wearing off by the end without more graphics to back it up. I expect that the rest of the visual novel will be presented normally, or else more graphics will be introduced? I'm sure at some point, the reader will expect to be given images instead of just text and sound effects.
The channel flipping could be interesting to see if it's applied throughout the visual novel, but I can't tell whether you're going to implement it beyond the prologue. Are you?
I am a big fan of the premise, but I didn't see much of the premise in the prologue. But I am hopeful we get to see more of the high school drama and the mecha action in the final product. And I'm getting serious (1990's) Evangelion mind screw premonitions here, so I expect this will twist up a lot of tradition, which I'm also looking forward to.
It's stupid that one design decision can ruin a whole experience, but what's done is done. I sense this is less than 0.5% of the visual novel, so my overall impression of the work is unchanged. I look forward to seeing more updates - and more graphics in the future.
