Overall good quality game but I gave a lower overall score cause there was no creativity with the theme. The simplest version going around with the theme is a snake chasing its tail. In your game, the goal is to eat enough to get long enough, regardless of catching the tail, which has nothing to do with the theme.
I would argue that catching the tail does have to do with the theme. It is a literal take on the Ouroboros. Furthermore, the fact that there are infinite levels and an endless cycle shows that there is also a take on the metaphorical meaning of Ouroboros. But thanks for the feedback though.
