@ gl.itch, I will look into a Mac version. I am thinking I can do it from Windows. I did do a WebGL, but it's unplayable until Unity does some work on it.
@ Team Gormless, I totally agree about the big level not being great. A friend told me that so I made the next 3 levels much smaller. I have no idea why shooting in the landing craft would do that.
@ elFlashor, I did want a HUD, but with the resolution limit I had to give it up.
