You need to thank Droid (Love of Magic), he put a demo of some AVNs on the MC's computer. Your's was one of them. That brought me her to buy it! I also got another couple of AVNs due to them being on the MC's PC in his bedroom in the LoM game!
Was in contact with Droid through the process and selected and packaged the content for him for inclusion into the game. Wanted to show that Callisto had a bit more substance than most VN's with the content provided.
I am thankful for any exposure, however don't typically want to bombard my players with demos of other games. Hence I have not really jumped into cross promotion.
