Game: Crystal Beans From Dungeon Explorer (Japan)

Oh, Crystal Beans, something like a dungeon crawler, but without the loot. I played it some years ago. You must pick 1 from 8 different heroes when you start playing. Each one has different statistics. After you defeat a boss, they drop a kind of power-up, the stat it increases depends on the color. 2 power-ups appear if 2 players are in. You may find some health potions, I don't remember how or when, but maybe if you defeat enemies. The crystal beans are counted as continues, you will find some while as you travel the dungeons. Lose them all and it's game over.
