Well that was a fun little game! heavy in RTP, but the humor was quite enjoyable. I really liked all the kitty themed items and the cat puns as well as the boss' scrolling dialogue. poor monsters, all bullying each other.
You might want to be careful of how much dialog you put in one line though. See the line that shows up as you type in the show text box in mv? It's to indicate that that's how much of the message will show before it gets cut off. There was some of the dialog that was lost because of it. Just press enter to make a new line before your words cross it. Also, it might be a good idea to raise the number of steps before a random attack occurs in the settings of your maps. They were just a tad too frequent.
But all in all, I thought it was good :D
