Nice of you to include multiple locations for your levels it makes the game a lot more visualy interesting and adds to a feeling of progression. I also like the additional mechnics to spice things up, and you seem to use them sparingly, so they don't overstay their welcome.
Unfortuantly, I couldn't get past the level, where you need to push the box into the water. I rolled into 6 on the finish field, but it didn't count. Still - great game.
