I am not 100% sure if this is the right forum to ask for some testers (if not the mods may move it to off-topic) but I've got an email from an user that told me the 64bit GNU/Linux build of my game RogueBox Adventures turns his screen black if he tries to start the game on his Debian9 system.
I don't know much more then this about this bug but I am afraid it happens to more people and scares them away from the game. On my system everything works fine.
I would love to have more feedback on this topic, so I would be very happy if some of you could test the 64bit build on their system and give tell me if it starts correctly.

Thank you very much!
