Hey there, thanks for playing! As written, this is actually the "hardcore version" I made years after the regular version. A friend translated this into english and we polished it later a bit, so the regular version does exist, buit it's only in german.
As for a FAQ, there is one for the boss fights inside the game folder I think. Unless I am misremembering something (or it was also only available in german and I deleted it, could also be the case xD).
