It wasn't the first game to utilize the concept of an auto-moving unit, but it absolutely popularized, and for good reason. A ton of levels requiring you to use the various tools at your disposal made this the most robust example of the concept when it came out, and the game did a great job on building your skills and ideas about how to problem solve as you progressed through the levels.

One of 4 DOS games my Dad got for us as kids to play on our Windows 3.1 computer.

I've always wanted to own/play this game. Now I do, and I'm enjoying it. :)

One of the games from my past that I could still spend days with looking at the creatures mining!

Hours upon hours of ingenious puzzles to solve. This is the first game I remember playing.

Hilarious and maddening

é um daqueles jogos tão simples que até uma criança entende o básico, que vai se expandindo em complexidade até que se torna deliciosamente complicado. acho que só não dou 5 estrelas por skill issue mesmo.
