Very good, it's very polished. My high score was 1.010 :D. I played until unlocking all snakes, and then an extra level (I thought maybe there was a little extra secret). Overall, the game is very good, you can't go wrong with snake, and I like how it feels sort of like Undertale with the different attack patterns and all.
The presentation is very good, animations are nice, and the only "bug" I could find (which probably is intended) is that, if you start a new game, after the mini tutorial, if your snake is on track to pick up a star, it doesn't until you move it again.
The music and sound effects were also very good. Congratulations on such a polished experience!! :D
