Soukaigi

An action RPG released by Square in 1998. Features music by Secret of Mana composer Hiroki Kikuta. To progress from one level to the other you must destroy red, yellow, and blue Garan stones. By destroying the Garan stones, the bar on the right hand side of the screen will go from RED to YELLOW to BLUE. To progress to the next level, the bar must be at least to BLUE. There are some crystals that cannot be destroyed, but you can come back to get them later. You can also make the bar go up by destroying enemies, but it is not as much as destroying actual crystals.
