I enjoyed this little game quite a lot. It's impressive to see the amount of thought and effort poured into creating this little planet of cats. I love how every cat had something funny or quirky to say, sometimes with changing dialogue which made exploring the whole world a worthwhile task. Running came in handy for skimming through the buildings.
What I found very charming was the colorful, animated text used for certain words, gives the game a cute, bubbly personality. It reminds me of reading old Geronimo Stilton books (children's novel).
I didn't mind the gameplay at all, personally finding all levels quite easy to score very close to %100. The final level certainly was quite difficult, which it should be, I had a couple goes at that. It was still manageable though.
Small issue is that sometimes the levels require all four movement keys to be pressed at the same time which is mildly awkward to pull off, since I use three fingers for WASD/arrow keys, but I guess you could just utilize more fingers to hit the fourth button.
Overall, I applaud the worldbuilding in this game and the unique personality given to it.
