While this game has a good concept, it seems you only really worked on a few parts, which caused major problems throughout the game. Bottom line, to complicated and not enough thought in some parts.
-0.5 for having catnip look like a green box
-2 for having the cats look like demented mice
-2 for misspelling catnip throughout the game
-1 don't know where the boundaries are
+ 6.5 for having awesome description.
So in all, 1/5
This is very impressive for your first game. Hope you make more. Also, I suggest make the switch button activate by pressing a key instead of clicking it.
