Surely there can't be any more puzzle and clone games. What's this? Crystal Mines? Looks like a puzzle game with shades of Pac-Man and Boulderdash.
Using either keyboard or joystick guide Sam through the mine to collect all twelve power crystals. Sam only has limited fuel and each move uses up one unit so plan your moves well. Move around the maze collecting the power crystals while avoiding the patrolling robots.
For some reason the game layout reminds me of Boulderdash, particularly the first level. In fact, the game could be described as a Pac-Man/Boulderdash hybrid. Graphics are really minimal and sound effects are basic bleeps. The gameplay is frustratingly slow, but if you have patience, the game might just appeal to you.
Second Opinion
Another puzzle game and another clone-ish game. Again, old gameplay doesn't always stand the test of time as shown here.
