An interesting role-action game with charming graphics and characters. Clear menus. The game has been adapted for mobile devices; it doesn't overheat or drain battery power. But even so, I only give it 3 stars. Why? It's not an upper-world game. Predefined tube battle locations. There are no chests with items to be found at all. Whether in the cities or locations, the only thing you can find are herbs—that's it. I personally think it's a shame. The graphics, along with the many invisible walls, make the game very depressing.
