I just played through your demo and here are my impressions.
I like the idea of the girl having to go save her pet cat.
The demo did have lots of spelling and punctuation mishaps.
Dreadful was spelled 'dreadfull'.
Butt was spelled 'but'.
There are many places where commas are missing.
Also, spaces are often missing before the next sentence.
Also, the text was oftentimes cut off when I played. I could still figure out what they were saying, but it did detract from the experience.
Is there a menu to the game? I couldn't access it.
Music fit well. I did like the outside snowy music.
I liked how the sprites were a bit different from the normal VX rtp.
Overall, I would say this game has a cute start, but could use a bit of polishing. I am curious to see more.
