Use the arrow keys to control the snake and the sliders to make the snake behave differently. I wouldn't suggest making the length too long, though; it glitches, and I haven't found a way to quite fix it yet. :/ Try not to stray too long on the edge of the screen, either. The color zero is default, which is dark blue. (Optimal performance: length 50; thickness 10)
This is my first pen project, which is not very advanced. I made the engine so that you can only make one turn at a time and have to wait for it to be completed before doing another. It's very simple and hard to play around with, kind of like using the [ glide () seconds to x: () y: () ] block instead of the [ change x by () ] block with a repeat bracket. I was originally trying to make a Snake game, but then I got kind of tired and a bit confused with the pen coding, so I ended up with this simple engine. Time to make: About five hours straight (I know, a little long for a simple project like, this, but this was my first time, and I took the more concrete approach since I'm not that adept with the mathematics used here yet)
