Build me a simple playable 2D pixel art game prototype in Unity, using the same style as this project. I want a character that can move, jump, double jump, run, and shoot arrows, with smooth animations for idle, jump, double jump, run, and shooting. Add a few basic enemies like a flying bat with a sleeping and flying state.

Please also include collectible items like coins and hearts, with simple shining and spinning animations, so the player can pick up coins and restore health. If it fits, add a couple of fun actions too, like bombs, a dash mode, and a ball mode, so the prototype feels more complete and playable.

Keep it clean and easy to test in Unity 2022.2.3f1. Make sure the gameplay loop is fun right away, and if you need to look up current Unity docs online for anything, go ahead.
