Hey back, I would like to show you guys a new script i found out there it allows you to play the classic game Snake by Martin O’Hanlon.

Here is a video i found on the page

Code:

Note! I changed the glowing obsidian aka ‘The Snakes food’ to a gold blocks because i was testing it on raspberry juice
