Livestream of the ZZT world "Escape From Mars" by Stephen Wooster (1996)
You and your crewmates have been captured by aliens. You need to rescue them and escape the planet.
What starts as a fairly bland looking action game (with a few creatively designed devices for killing humans) expands as scope as you escape from the base and explore more of the planet itself. This one was a definite winner where the visuals get quite impressive for a game that doesn't use ZZT's full palette of colors. Some fun characters and great artwork towards the finale as well.
