Or you could try the next thing up from ZZT, MegaZeux.
Newer versions and forums where you can get help on it are at
www.digitalmzx.netI prefer it over ZZT because it runs better, and I know a little on how to use Robotic (The coding system) effectively (Like drawing a HUD). MZX Is basically an upgraded and more advanced ZZT, and there are many games you can dl from the DigitalMZX site too.
EDIT: And just to add, if you want to look at an awesome game-in-progress for it, go to the Journals forum and look at Hive World.
