I found a nice looking sprite sheet over on open game art.org, so I wired up player walking animations. I also made a simple map using Tiled.
There is also a simple scene manager, which lets you move from the title screen to the first scene.
Everything is pretty crude, but I find that I'm making a ton of progress due to the constricted time frame. I've rewritten a few standard processors that I've written many times before in other games, and was happy to realise that I was finding new tricks now that I'm not obsessing over the code too much.
