[RPGMXP] Snake Mini Game

I would like to make a snake Mini Game

Spoiler for:

example http://www.snakegame.net/phonesnake.htm

The only thing I can think of is use a caterpillar scrip so
1) is there caterpillar scrip that has an unlimited party size and can be disabled
2) how to disable the menu for the mini game
3) and to make the actor keep moving in one direction (For example)

Spoiler for:

The actor starts moving left and keeps moving left until he hits a wall or the player moves the actor in a different direction

thanks for all the help
