I have some love for these early, arcadey NES games but this one is just way too limited and repetitive for me.

An interestingly complex puzzle game for the NES era, where understanding and exploiting AI behavior is crucial to solving the puzzles. Sadly, the AI isn't always fully deterministic, and there are action-y elements that should've been cut in the transition from arcades. Still, it's nice and thinky, lets you jump in and out of puzzles to retry or switch with ease, and even includes a level editor. A light, fun part of the Mario history that doesn't deserve to be forgotten.
