Impossibru's Blockoban is a set of very clever puzzles. The object is to get your man to pick up the jewels. Slide your man -tilt maze style - all the way to the end.
Your man cannot go over a bush. As for the grass & water, you will need to slide platforms.
I played about 12 levels. They're challenging! The graphics and movement are too slow and sadly, this makes the experience less enjoyable. But the puzzles themselves are good.
