Sure I guess what I can do is "sprites, ideas, possible sound effects," but if came down to though I'm not best at, would be coding at some level of degree. I would need to join a person or a team though. :)
Ah, right. Working in teams is awesome. If you need people to work with and haven't already joined, I recommend joining Jonas' Discord server and ask for programmers who want to work with an artist & sound designer. Lots of programmers there :)
