The Dragon's Castle is a rather unique graphical adventure game done completely in BASIC. While it has a very limited vocabulary, and being written entirely in BASIC means the graphics and text draw fairly slowly, the graphics actually have scaling built into them - this means that trees or brick walls, etc. of varying sizes are drawn, and can get bigger as you approach them. This was meant as a bargain/beginners adventure game, and your mission is to get rid of a Dragon that has taken over the Princess' castle. There are a few creatures to deal with, including the Elvish Imp who likes to steal your stuff.
