My main problem when it comes to programming is that I always have a desire to do things in the most high-concept way I can fathom, which leads to stress and eventual abandonment when I realize my perfectionism has taken over... It was very nice to see this sort of approach to programming in Pico-8, and I feel like I should be well equipped to make a simple little snake game!
This way of programming is really good for smaller projects, but not larger ones. You'll soon get lost in thousands of if/then loops etc.

Biiiig thanks! I actually had to watch it on 0.75 to duplicate every line myself, to learn how to code. I'm a super begginer and I searched for snake on Pico8 and I have to tell you I'm very happy you made this. :)
Great tutorial! I would love to see more tutorials for games like this. Question about the tables: Why do you write the code as snake = {} followed by snake.x=3, snake=y=2 etc... instead of putting the values inside the {} as snake={x=3,y=2}?
Thanks for the kind words! Functionally both methods of adding entries to the snake table are equivalent so you should go with whatever you prefer. I just arbitrarily decided to go with my way :^)
lol it took me like 3 days to get my own version of snake :( i am still having trouble with making the controls "roll' instead of having to hit them on the right game tick
grats on getting your own version done! and yeahh, buffering input is a tricky problem but there's two approaches you can take. 1) whenever player inputs a move, let the next frame be a game update. this will allow a player to easily chain direction changes, but has the side effect of actually speeding up the game when a lot of inputs are activated. 2) have a move queue. each time the player presses a button, place it in the move queue. each snake update pops and does the next up move if the move queue isn't empty. let me know if you still have troubles. maybe i can word it better or give you some example code :^)
If it helps, the easiest way to go about this is probably a 1-key input buffer. What you would want to do is have a global variable that you use to store if an input key has been pressed. Then during every update, before checking to see if the snake's tick has counted down, check to see if the player is pressing an input. If they are, set the input buffer to that key. Then, whenever the snake's tick is triggered, check to see if the buffer variable is nul. If it's not, set the direction and make it nul, otherwise just move the snake in the current direction.
