Dot Valley is a arcade/puzzle game based on the concept of Boulder Dash. As a miner, you dig for diamonds, but must beware of falling rocks and hostile creatures that you ay come across. You have a limited supply of dynamite and bombs, which are to be used wisely to clear away obstacles or deal with monsters. To complete any level, you need to collect all diamonds. Dot Valley was originally sold as shareware, but now you can get the full registered version from the author's website (please see the links section below).
