The ./setup.sh ran ok, but both the ./play.sh and ./debug.sh basically freezes my computer (the ./play shows an overlay with some numbers downloading something, but it's just the text and nothing else, outside of the of the console window). Anyone else has experienced this? I'm on Ubuntu 16.04, 64-bits, i7 7700HQ, GTX 1060 (8 GB), 16GB Ram.
