I got it to open on GNU/Linux by renaming the folders as suggested. Unfortunately my mouse could click anything on the title screen.

Is suprisingly pretty and runs decently well. Shipbuilding is a bit weird and it seems like you can build either up and down. Any plans for T or X-shaped parts?

Ships couldn't dock to my spaceport. Dunno if it's a bug or the game is incomplete. But I like the orbit simulation, looked good! Looking forward to see where you're gonna take it.
