Couldn't move, maybe it was because I was using the wine emulator, maybe look into that!
Oh no! I'll be honest, none of us have a Linux system so we did not do any testing on that. I'm sorry you had that experience. There was a review on the submission that mentioned they had some stutters during certain spawns but they said it could have been due to them using the Wine compatibility layer.
We'll try to figure out a way to test the game on a Linux next time though, thank you for the feedback and sorry you couldn't get it to work.
