How do "Steam Collection Cards" drop in this game? I finished the game three times. I left it open in the background for about 2 hours, but not a single "Steam Collection Card" was dropped. What should I do?

Hope you can add Achievements, thanks.

i dont want to hit a mouse button everytime i move to next dialogue

first of all, thank you for release Roommate Corruption on steam. i'd love to play adult game with sexual contents. high quality 3DCG rendering? it's looks like awesome to me. but also i tend to enjoy 'Steam Achievement' system as well. so i wonder dev, do you have a plan about it? please, could you leave a comment anything if you watch this write? i hope you always have a good day with your valuable people dev ...
