Congratulations on the first Game Dev jam entry! :) Hopefully the first of many!
Ah, I remember Snake! Well done, you made Snake, and got it working! A great fit for the theme.
I actually tried reversing into myself right away, just to check if I needed to be careful not to accidentally do that later (it's happened before). It didn't cause an issue, so it seemed fine. :)
Nice entry, well done!
