I just started working on the source code for my game yesterday, and it's got a long way to go.
Thankfully, I decided to make my game have minimal graphics because I'm doing this alone and I'm much better than coding in C++ than I am designing character graphics.
Script:0%
Code:3-5%
Music:0%(I probably am just going to download free music or cook up something in garageband)
Graphics:?% (I create graphics when I need them or I just use shapes)
Then again, I expect my game to only be a concept of something bigger to come.
