I've been trying to put my finger on why this game strikes such a chord with me, and then I realized that it plays a lot like some of my first ever Klik & Play experiments! The shareware demo of KnP didn't let me use the Event Editor, so I resorted to what the Step-Thru Editor let me do: object behaviors mostly related to object collisions which created new objects as a result. The puzzles in here are object interaction puzzles, done in such a way that it feels really nostalgic to me.

I especially liked the method of unlocking the secret.
