So you knew nothing of unity or C# at all? O.O Then I must say I'm even more impressed XD
I think making small games like this will give you a lot of experience. Though if you are doing this as a hobby, then the most important thing is that you enjoy doing it :)
If you need some help, I am part of a team with a developer and artists (2D and 3D). And I am the designer. If you got some questions concerning any of those diciplines, maybe we can help?
Keep us posted!
