I'll be quick and honest:
The animations were unexpected, smooth and surprisingly appealing, and they're top-notch, especially for a VN. I would've almost said I was watching a movie.
This brings me to my second point. It's very linear, more akin to a movie than a game. All the choices I have seen in 0.2 feel purely cosmetic, with very little to no impact on the story. If that's what you aim for, then there's no problem.
For the third point, I have to criticise the writing. The content, story and pieces of lore are very interesting, however, all immersion is broken by the phrasing of some lines. To be honest, some of them were painful to read. It was not really about orthography or grammar as much as it was about the structuring of sentences and expressions. If you're interested, I can look again when I have time and write down the worst ones.
The fourth and last point: characters. It's too soon to say whether they're good or bad, hollow or well-made, but their dialogues are... generally bad. Many lines are dry, many reactions are weird and many dialogues seem so emotionless, or full of fake emotion, that I wouldn't be surprised to see it was two AIs doing the talking.
The game is good and has much potential, but as with any game at the beginning of the road, it needs time, effort and polish.
