Devil Stone is an RPG which can be played offline without extra charge. The story is about Phicus Sera, the successor to the throne of the Underworld of the tenth generation, being sent to human territories after being deprived of his power by the old Devil King.

To find the fragments of Devil Stone, scattered all over the continent, regain power, and succeed the throne in the Underworld, Phicus encountered Eiji John Austin, the Champion of the 19th generation, and joined Eiji’s team to adventure into the Underworld.

On the journey to adventure with the Devil King and the Champion, the conspiracy hidden is disclosed little by little. Everyone in the team has changed as well. On Lux Continent, the Champion fights against the Devil King, and the story is going in an unforeseeable direction.

Whenever the Underworld Crusade Team reaches a new location, different events and missions will be triggered. In quests, you will bump into all kinds of monsters!

This game shouldn’t have been released until majority of the bugs had been fixed.

Bugs squashed, worth a play

This game has a lot of charm. Art and sound design are very good. The UI is streamlined, it’s nice to be able to tap away to close a window instead of having to hit a close button. Things like that add up.

The story is better than I expected. English translation is has a few poorly worded buts, but everything is understandable. The characters are not generic.

My criticism is more around the pacing, difficulty, and battle strategy options. Levels are easily made so you hardly need to use potions or healing spells aside from a later boss battles. New weapons are available too quickly sometimes and for not much improvement, so it can be better to wait to upgrade. Phicus’ 2nd skill ends up outperforming his final skill, so I think there should be some balancing still. But there are no buffs or rebuffs, no elemental components, and your companions only end up with two skills, so strategy in battle is really simple. It could use a greater difficulty mode, but since there isn’t much tactical potential I don’t think it would be worth it.

This is a casual rpg with a good story, great art style, good controls and sound design. Taken at that, I think it’s worth a play and will buy the sequel.

(I’ll add that I sent the devs some of my bugs I found in the previous version, and they responded appreciatively. then responded again a few days later to let me know the update was out. Classy!)
