My first playthough was pretty frustrating because I hadn't done a slide puzzle in a long time and I'm embarrassed to say it took a while to remember how to solve them lol. That said, I think the use of puzzles that differ based on what class you get was a great feature.
I enjoyed the story and the lore of the cat clan. The writing was good and like Neverdusk, I appreciated the extra details that could be revealed. Sadly, I never figured out how to get a "good" ending even after three or four playthroughs.
Overall I think this is a great game! I did encounter a couple minor bugs (where it looked like it was trying to substitute in a name but showed the code instead) but nothing game-breaking. The presentation was nice and I liked the music, too--it was sparse but really fit the story.
