Experiencing the same thing, tried both the alpha and the other download. Big oof.
It happened to you too? Do you have any extra information to add? So when you launch the game, it shows a black screen, sound plays, and prevents you from leaving/tabing out? Do you have a graphics card and is it old or is your monitor aspect 16:9? Sorry for asking so many questions as I want to solve this before more experience this problem.
Edit: I think I found the cause and I'll get the new version out in the next day or so. I think its because of a conflict with supported resolutions when the game enters full screen mode, thus I'll release a version that is windowed instead to test if this is the case.
Thanks for your time.
