Originally a java app, it was ported to android as a learning endeavor. I have released it for free as my first app, to test out the entire app process. You have a few input fields, one is where you put commands to walk around or do actions. Try b for boss, which starts a boss fight. The other two fields are name and class... There are predefined classes like mage, healer, fighter, and thief. There are some functionality limits, like starting the game over with each command; and no saves. But it is playable.
