Quoted from gouveia:
I can't make monkeys all day, unfortunately. That's the main reason I won't take anybody's money until I've got something to sell. If this whole thing stopped tomorrow people might be disappointed, but no one would be chasing me with pitchforks like Andrew Heighway. At least I hope not.
Dude that is totally an honest way to go... look at all the people who gave Spooky Pinball money and haven't seen a game in a year. I think that is totally legit way to go. I'm on your list for a money and I've been begging you for a witch/smoke for over a year. So get me on the list. What a stand up guy!
I can think of a couple more mods...
1) Much like the railroad track for walking dead or ACDC how about something like that but its a yellow brick road to snap on over the ball rail that has munchkins on it?
2) How about replacing the emerald city with a mod in the back of the game using a small LCD and a raspberry pie so a city as big as the game will fit and in the middle video of the wizard. That would be cool.
3) The witch on a broom would be a cool mod.
