Hi,
I have searched for some text games in google play and this title just caught my eye.
This game has two versions - lite for free and full for about $1, so price is fair.
It is a simple fighting game where lots of things are just random. You answer some basic questions about your hero and it is generated for you.
And you can start to wander the world. There are some image buttons but their text description precedes them.
Try it and report your experience, I am going with full version probably, because 20 CZK is simply very good.
