Thanks for the kind words! Itchio is the complete version that doesn't require patch. Steam requires a patch for the R15 portion, otherwise is SFW. You can find it here: https://aikasacollective.com/support/
I downloaded the patch and got it installed, but I'm not noticing a difference between the patched version and the one without the patch. I know I have it installed, because under 'mature content' it has 'on and off' instead of 'disabled', but so far I'm not noticing anything. Does the R15 part just not come in until the very end?
