A really cool game!
Pros:
1. It feels nice to slowly unpack (or pack in this case) the puzzle behind each level,
2. Once you understand the rules behind cats you really feel clevel,
3. Cute art.
Cons:
1. Cats could "hint" their behaviour more with how they look.
2. It felt weird that in the second level I had to "waste" the first cat. Looks like it's not always a box for everyone ;(
3. I would love to get some "hint" while hovering over a cat. Maybe after winning the introductory level with that cat, their behavior could be displayed in a hint. It's hard to keep track of all behaviours and solve the puzzle at the same time.
