Has anyone given thought to making some spectator levels? I find it a bit more fun personally to make levels that run by themselves, physics interacting to perform the final solution in a display of action. I've made "This Level will Self-Destruct in 17 Seconds," where every piece destroys itself after being used in its proper way, concluding with the goal cloth at just over 17 seconds. I like the idea of a crumbling stage as the armadillo races to (perceived) safety at the end.
Does anyone else have a concept they've been playing around with for a spectator level?
