Yes, yours is not the first game I tried to play with the same mouse issue on FF, that's definitely not your fault. And for the windows build crashing with wine, well, even less your fault, as it looks to me that wgpu is calling into a stub DLL (not yet implemented in wine). I was simply dutifully reporting what worked and what did not.
As for the general criticism, I want to make clear that it's a very solid result for a single-dev game. Good job! Budgeting time is something you have to learn the hard way!
