I'm a bit rusty, but I'm also know of C# programming. Could do 'some' pixel art at a stretch, but far more confident in programming over art.
If you're still looking for another coder, throw me a message then at ArcaneHermit#3896! :)
PS: As an aside. You might also want to look/find a basic musician for 'sample boss/battle' fights as well. But if it's a small dungeon crawler game, probably only "Battle" music at minimum. To possible Ambient (SOUNDS!) and such at a stretch.
