I played the game and decided I'd leave a quick review:
The gameplay is fun and easy to get the hang of. It's pretty basic but I enjoyed being able to lay catnip around the level. The bombs may be a little bit overpowered, as I found myself killing most of the cats on my third play-through.
The controls are explained right before starting the game, leaving me with no confusion as to what I was doing. This is great because anybody can load the game up and know how to play.
I appreciate the different level backgrounds, it adds a bit more variation to the levels. Most of the backgrounds are good, however the final one is a little disorienting.
The art did it's job presenting a cute and fun environment, as did the sounds. I'm not sure what to think about the Kevin Macleod music. It never really got annoying because the current song changes depending on the level, and because the game is quite short. The little mouse moving around in the title and credit screens is a nice touch, as with the splash-screen.
Overall, this game is simple but fun. The only real issue I had was that pressing the escape key would return me to the main menu, as apposed to pausing the game. It didn't really bother me that much because the game is short.
