Hey I appreciate you giving the game a shot!
Sorry you started not to feel well after a while.
We definitely have a lot of bugs to hash out. I appreciate you taking the time to write out this thorough comment, it will help a ton in debugging and making the game more accessible. The cursor, tutorial, and mouse sensitivity will definitely be fixed in a future patch.
as for motion sickness, my brother also gets it while playing certain games, so I'll be sure to consult with him and the team to see if we can come up with some ways to make it more accessible.
Thanks again for trying out our game!
