Livestream of the ZZT world "Tough" by Matt Dujnic (1996)
Well. It lives up to its name. A colorful world with some fun effects and animations. Lots of secrets, and way too much danger. A lack of health other than a pricey shop makes this one frustrating to make any progress in and you'll frequently make your way several boards deep into an area only to reach a locked door you lack a special key for. The puzzle design is pretty good though!
