Bosses are already planned, but they're comin after I get all the mechanics down for the rest of the enemies.
I'll be getting a HUD in there once I can take a better look at how SDL_TTF works. I've been looking at the sources you released, so I've been learning a bit about it.
I don't plan on doing scrolling backgrounds, however.What I plan on doing is having each level be a different 'scene', with a boss at the end.
With college daily, and with family members watching television during the day, I have a hard time getting a lot of work done at any one given time. I'm pleased with the progress so far, though.
