I found out about this game yesterday evening and i already tried it. There could be few improvments, but i really suggest players who love this kind of games, to try it out.
Im already lvl7 in game 
(played only 30min, hehe )
Tho, im not sure if European and american players can play together, but ill try to find it out.
I believe its possible to make a clan, but gotta find that out aswell.
Hope to see ya in space or sky
