For the most part, these are less full-fledged test levels and more ideas, suggestions, hey what if test levels tried doing this too? And viewed that way they’re pretty interesting. The timing required can be incredibly finnicky to the point of feeling random—I could never climb the fencer tower without setting off two at once—and there are lots of moments that would work much better with some scripting, e.g. to keep me from dying, or to restore Uterus’ spike balls, or to get around the need for all those smoke rings. But if you abstract away from the implementation, with its bare-bones graphics and its empty win areas, and think about the ideas being presented, then sure. Maybe some test levels could benefit from things to stomp (that don’t lock up the camera after a while), or some of the other funny tricks that are presented here, albeit preferably with a little more forgiveness.
