Hi! You should message Steven Zas, he made the original Demo and is very interested in the development of this game

Glad you contacted, I'm Gestoski, I'm the lad who went out of bounds in the original games, has ownership of the unused Zombotron vehicle game, 1st place on the Zombotron leaderboard for highscores and plenty of other things, I think Steven has other things to worry about, afterall, he passed ownership to the project, I'm not exactly sure what Darwin is doing, but I hope progress is doing alright.
