I just baught the beta (2016-04-07).
Congrats ! It really feels like the good old version 1.24 Blackshift.
One problem: I understand you may need internet connection during beta testing for telemetry, but please make it stand alone once out of beta. Internet is no safe place for kids and there is no reasons a game could not be playable offline, at least for single players.
(By the way I didn't noticed the old Blackshift from the XP times failed in Windows 10. Last time I checked I was under Windows 7 x64and it worked great. Good idea to rewrite it for modern OSes)
