Okay so another update: No pictures of progress just yet I'm afraid.
I finally built a background out of tiles and have worked out scrolling the level, and I've done some preliminary work on enemy waves, designed a new enemy, and have been getting code together for them to shoot at me too :D Gonna be working on the getting damaged code and also trying to work out how to make a sprite "flash" when its hit and damaged. this was giving me some trouble until like 2am last night so I called it a night, and I would have done more work today but I got home from work SUPER late, so... tomorrow will be coding day :)
