Thank you for the feedback!
The camera is shifted towards the boss while making sure the player's still on screen. Maybe I could lower the factor for the maximum distance from the center of the player's ship.
The fullscreen option was requested to have it not occluded by the text on the game page. It's still fixed in size though because it would break the UI otherwise atm, I'll adress this in a future version and make it resizable. It was quicker to not worry about this for the jam tbh.
The map bounds will be adressed too, maybe even removed in an updated version.
