Really fun game with a few tricky puzzles and great background music. Love how it feels somewhat intuitive just from the way you built on the classic snake game, and the approach to the theme where you have to create a loop to beat the level is very unique.
A minor critique is that it was somewhat overwhelming having every mechanic introduced at once right at the start, it'd be much easier to absorb if mechanics were explained right before they appeared in the next puzzle. Would also like the menu buttons to be navigable by arrow keys since the snake is moved this way.
