About RPG Antiquia Lost
Play to the end of the game for free!
An authentic RPG of a journey with a girl made of slime!
Bine is a young man who lives in a small rural village. One day, he is asked by Lunaria, a girl who lives near the village, to go with her to the royal capital.
With more and more disappearances occurring, the rulers' reactions are mixed.
And there is a forgotten existence, too...
'Trusting hearts' become 'strength'.
This is just the start of the story...
The heroine, slime?
The heroine is... slime!
By eating gems, her statuses are strengthened, and she can learn new skills.
In battle, she has a powerful death-blow skill: she can mimic monsters!
Put different characters at the head of the party
Special actions, such as smashing rocks or squeezing through narrow gaps, are possible, depending on the character at the head of the party.
Try to find all the hidden items!
Plant seeds and harvest items
By planting beans in plant pots, you can harvest many different items. Every now and again, you might grow something incredible!
A wide range of achievements
The game features many well-loved achievements, including weapon development and arenas where you can fight against strong enemies.
* The game can be played in its entirety without the need for in-game transactions.
* Please contact us through the Contact button on the title screen if you discover any bugs or problems with the application. Note that we do not respond to bug reports left in application reviews.

* A Premium Edition that includes 1000 bonus in-game points is also available for download! For more information, check out "Asdivine Cross" on the web!
