Cats!!!!! I loved cats! The game is great, graphic is great, generally the game is great. I would say a bit hint, like how combining elements should work, or how the level progression works would be nice, as when I first got into the game, I am quite lost and was overwhelmed by everything that is there. It doesn't affect much later on though, as when you grasp how the system works, the game just become more and more enjoyable.
So that's said, the game was just expertly made, so a job well done!
