Okay so from what I understand, Indexing colors makes a list that keeps track of colors by the number that's assigned to them when they're added.. so basically if my first color was red and I put red all over the image I could decide later I want it to be blue, change it in the index... list? and the red in the image would turn blue without having to redraw it? If so that sounds like a very useful thing to have, thanks! The right colors for me are bright and colorful, very cartoony. I've always kinda preferred that to realism so I'm not looking for a large amount of colors, I'd kind of prefer to stay true to old limitations but I'm kind of fuzzy on those too since it seems like it's different for every game they used to make.
I'm glad it reads well in general, I'll be making adjustments and posting a new version soon. I'm not sure how to portray perspective in this situation so I didn't give it any thought, I'll try to figure it out! The idea is that it's a side scrolling game that the main character flies around the screen and enemies come from the other side and you have to shoot them, kind of an old arcade game where the only goal is to get a high score.
(Edit) Okay I added a bit more to it and did a couple of the suggestions. I want to work a bit more generally and then get into finer details as I go because I don't want to over develop any one part. I added a sort of 'mid-ground' to break up some of the furthest background but I'm not sure it addressed any perspective issues.. If anyone needs to please feel free to scribble all over it! ^^;
(Edit Edit) I tried moving everything up a bit in my latest revision and that seemed to look even better! I'll probably include that in the next update!
