My proficiency in Java, a primary coding language for Minecraft, combined with my game engineering expertise makes me an ideal candidate. I have created many unique game mechanics, some of which align with your requirements such as new player abilities, and I will bring this creativity to the table.
Moreover, my understanding and experience in managing backend engines and game servers bode well for this project's scalability.
