Dwarves in the action. Two of them need to get through levels in the Sokoban style. If you want to enter the exit you should collect all the rings at first. To reach them or destroy enemies just push the boxes. They can block or kill enemies, plus they float in the water so you can use them for building the bridges. Many levels are about controlling two guys so if you have any friend you can play together. The game was commercial creation so the graphics look great.
