Download Question

[maniacbadger]

I'd like to buy from the frictional store so the developer gets more of the money as i know steam takes a cut but does the version from frictional games have any DRM?

Secondly can the frictional games version be burnt to a disc as my internet cuts out for short periods of time and could be irritating if i want to reinstall at a later date and my internet is out

Also is there any word on a retail version in the UK?
