The land where the two men and women had landed.
There were no figures on the ground, only strange moaning sounds.
It seemed that something was happening to this land.

There are many structures on the land that seems to have been built by humans, but there are no people in sight.
Why have these two people landed on this earth?
What is going on in this land?
The story progresses, shrouded in mystery...

This is a game that you can play by completing the main story.
This game is an autoplay RPG game when you're working on the main story, besides you can tell it to level up or collect materials and leave it to collect materials on its own.
Enjoy the adventure by using the monsters and materials you've added to your team.

Also, in this game, you can make things you need for exploring by processing the things you get from exploring (leaving them alone).
Use the "materials" you get in the game and the "money" you get from exploring to make weapons and armor to build a stronger party.

Quite a good game

Edited Oct. - After playing this game for almost a month, I still keep it 4*. The game progress is slow and seems to be slow regardless. I am now in the 3rd map but I still have only 1 team. Clearing a story location isn’t that easy. I kept all my building up to date. I will see what the new update will be. Another idle game with quite an interesting system. I am playing a similar system and this one seems to be its sequel which has an improve game system. Similar to its predecessor, the game starts very slow. It takes a long time to progress. I have a feeling that I will hit a wall at some points like it’s predecessor. The system is an improvement but is still awkward. I am giving the game 4* for now until I am into the game further.

It a good game but it hard to get the Materia to upgrade Blacksmith. Or it only give you one. I already on map 6 and still on level 2 on blacksmith. Can’t get anywhere anymore. Because you going to need to craft stuff to keep going

Has a good beginning. It a wall and can’t seem to get past the second map stage 2. Otherwise great game.

Update: The developer makes frequent updates to this game and the changes are nice. I have enjoyed playing this a lot.

I hope the developer would make a sequel to RPG Vanatis as I loved being able to hire adventures how that game worked.
