Level up very fast, all purchases add cash, using skill points gives you more. The game is 23 MB it will load slow. Unfortunately this is a demo so only 2 dungeons are playable.
Dungeon King Hacked
You are trapped in a dungeon. You can either choose to stay there and die alone in that lonely, scary place. Or you can fight like you have nothing left to lose, defeat all the monsters guarding the place and then defeat the dungeon king to escape.
