Unnamed-blob-game DEMO: added doors, backgrounds and TRIPLED the resolution

I added doors to to the entrances and exits. I also created a background and noticed that the spikes were missing and outline.s But thats fixed now.

I need more levels, so i haven't been working on the game itself that much, instead I've been making a level generator. This new generator can with the press of a button generate fully fletched dungeons - not yet though :(
