I remade the demo. And yes, I dropped the cat charade.
I remade the levels, so they are non-linear and way harder (you will need save states). Also, this is an IPS patch now.
If there's anything that could be worked on, reply with it and something that could fix it.

Munchers in "Horse's Great Pokey" now are on blocks (except the munchers that are being stood on by the Pokey)
