Yeah I made it.
Here is the Demo for download.
I should tell you, because I wanted the game to be farely perfect for the demo, I did have to change some aspects of it (such as taking away Munch zapping you for hitting his babies, there was glitch that meant Munch wouldn't stop zapping you.) There are also a couple of other changes made but I have compensated for them by adding a new screen with a new Character / Enemy for you to defeat in it.
Here is the Gamespeak:
Hint: Keep the gamespeak key pressed down untill Abe has finished talking or the other Mudokons will talk over him, rather than after him.
Press
0 - Chant
1 - Hello
2 - Follow Me
3 - Fart
4 - Whistle 1
5 - Whistle 2
6 - Wait
7 - Work (Has no use for the demo)
Enter - Smack
When playing as Munch, press:
H - Hello
Hint:
It's not just mudokons you can talk to... A certain Gabbit understands your gamespeak too.
