YES, I like to have a look inside of Black Forest Games!
I remember playing The Great Giana Sisters on my 'Brotkasten' C64! I spent quite some time playing it.
I also enjoyed the great music and was immediately fascinated when discovering Project Giana and hearing the great sound of the current trailer!
So I am a backer - of course
In my C64-time I was a young pupil and during a trade fair -I visited with my dad (I think it was the 'Hobbytronic' in Dortmund)- I was able to buy one of my very first CDs: The 'Shades' album of Chris Huelsbeck (
http://www.huelsbeck.com/shades-album/) and I still have this CD in my shelf!
So I think - if I have the chance to meet BFG - I will meet some interesting retro-inspired gamers and developers! I bring my Shades CD, do you still have a CD player ?

Yours,
Turtle (I discovered also a turtle in your trailer while Giana performed a twist, nice!)
