welcome to the forums, criminala!
thank you for your feedback! but plase bear in mind, that the even the latest alpha is 7 years old now.
most of the technical stuff is outdated, so compatibility issues are very frequent.
we have plans for completely rewriting the game, with up-to-date technologies, so the mentioned problems will be corrected automatically.
as for the sounds, please don't expect too much sound from the game, we have to make a working game first, then create a lot of visual content (models, GUIs, etc), and sound effects may well be the last to add. music is always a copyright question, so this will only come much later, too.
