Hey guys,
Small update and a quick apology from me.
While trying to fix the Clownfish bug, I accidentally uploaded a broken Steam build that only included the .exe file instead of the full game files.
Because of that, for a while the game was missing the files it needed to run properly.
So yeah... this was just me having a very professional clownfish moment.
The proper build has now been uploaded, so the game should work normally again.
If Steam does not update the game automatically, please try one of these:
Restart Steam
Verify the game files
Reinstall the game if needed
Sorry for the inconvenience, and thank you to everyone who reported it quickly.
