I like the graphics and music - It's feels really upbeat and cheerful.
The score mechanic is quite clever, as you need to balance filling up the bar, avoid making an obstacle of yourself as you collect fruit, and build up the multiplier to make maximise each fruit.
The controls feels odd at first. You're more inclined to press the wrong direction as the WASD layout doesn't intuitively translate to an isometric directions, moreso when you are frantically trying to eat fruit within 20 seconds. I do like that the game is forgiving when you run into yourself.
I'm mixed about the movement. On one hand, a tile-per-keystroke is extremely helpful for getting around within 20 seconds. On the other hand, all of this is being carried out by the left hand, so it cramps up your hand quickly. A possible solution to mitigate this may be to have more fruit instances appear on the field or have the snake keep moving forward quickly and limiting the player's inputs to turning left and right. Maybe the snake can move forward in rhythm of the background music's drum beats.
A game about a happy snake making juice to some swinging beats.
