Well,

I downloaded the windows version, extracted it, and when i click on the game, the menu open and everything works fine. but when i click on "OK" it wont open. I get this error

what should i do in order to play the game?

There you go, enjoy your 10$!

Oh cool, probably gonna buy!

edit: i just hope you don't ends up like notch and wont deliver half the stuff you promised ...

Notch has promised so much good stuff in minecraft. He didn't delivered.

I'm soo impatient to see what mythruna will be like!

Also stuff i would like to see:

Wires or redstones
why not making triangle bloks to make the world softer? ** see picture
more then 4 ores. i.m getting bored of iron gold and diamond ... + gold is totally useless...

A bit harder:
Space travel? Public server would be a planet on their own, so you can travel from a server to an other... (this would be trully epic)
or just a mmo server


EDIT: Spreading the word! My friends already know about this game we're all going to insta buy.
