We both kept working on the program. He created more and more levels, and I improved the strategy and the user interface of the program. There will be a free download at the end of this page. The game consist of different levels. First, I'd like to introduce you to the most important characters in the game.
Diamonds are valuable.
Killer Frogs want to kill you wherever they meet you. But you can kill them too, just smash them with a boulder or diamond. The Butterflies are deadly too, but when hit by a stone or diamond, they turn into a 3 by 3 square of diamonds. A Sieve magically turns boulders into diamonds. The only way to remove the brick wall is to blast it with an exploding frog or butterfly.
