I got the same bug Lutz had. At some point I just couldn't move, only turn. Found 2 (3 if we count first one as egg) golden eggs before it happened. Was searching for a password for a medbay lvl1.
But for what its worth - when I launched the game I had another bug with movement. I 'could' turn and walk, since at the bottom it was writing how I was changing directions... And I could interact with objects that clearly was not where I stand, yet camera didn't move an inch. No turning, no moving... quite an odd bug and it didn't appear when I restarted the game.
I aslso had to unplug my gamepad, since it was giving odd drag. Camera would start moving ever so slightly left or right and even diagonally.. sometimes it would force turn me as well. Felt like drunk person moving and for a while I thought it was intended too!
There is a huge difference between what we see and what we fight - I think it would be better to keep pixel-art enemies from the world as enemies we fight in the battle as well. It just looks like a huge difference between how it looks while we walk and how it looks while we fight.
I was reading logs. Second one was funny too... but bug prevented me from exploring further, sadly.
