I'm really sorry, I tried as much as I could to give the game a proper chance, but there were just too many bugs / weird elements I didn't understand.
First, the sensitivity is absolutely bonkers haha, and there was no option to configure it so that was my first struggle.
Then I killed some of the enemies, but at some point I didn't see any left and nothing happened? Maybe I missed one somewhere, but I looked around the map multiple times and didn't see any. I rebooted the game and could play 2 waves this time, but at some point I got attracted to one of the planet's gravity, and from then on couldn't ever leave it. By sprinting and jumping I could get far away from it, but then it would still pull me back.
