1) mixels (background resolution doesn't match item resolutions not saying about snake itself)
2) no powerups or anything, like wayys too basic, been already playing snake-like games with more features like different items with different behaviour on snake (speed, length, color, etc…), walls, levels, wrap-around and even portals :/
3) that snake doesn't even boost after time, literally a game a kid could play. unless you meant for this game to be an easy game, but i doubt.
