its a great game can you make it work on mac
also can you make it so you can close the ship designer
I do not have a mac to test with, nor any experience with them. I will do some research but I had assumed a web application should be fine on either.
It looks like you are very over-zoomed in that image - try using the new UI scale option, or using ctrl-mousewheel or mac equivalent to reduce the browser zoom to fit everything on screen. The ship 2D visualizer should be the bottom element with everything above it.
