Hello! Unity programmer here! I'm super well versed in Unity, if I had to put a level on it I'd say I'm advance intermediate, take a look at my profile to see some of the simpler game jam games I've worked on. I love surreal artistic games with weird stories, and I can do 2D and 3D. I can also 3D model, and create 2D renderers of models for 2D games as well. I can also do simple 2D designs and texturing, nothing too advanced, mostly because having a deep understanding of how art assets are created helps me understand how to utilize them best in Unity. I'm currently in school for software dev/game design, and work full time, so I don't exactly have lots of free time, but I'm very quick in Unity, and already have a large amount of pre made modular systems I can drop in games, edit a bit, and make work for the project. I've worked with a few groups in the past, so I can also offer some insight on how these things often go, and its good you already have so much planned out ahead of time, lack of planning or coordinating collaboration is what kills these projects most often... I'm also really good at project management and can help with that as well.
