I am really enjoying the game, and although I am not supporting it on SubscribeStar, I would like to leave some recommendations.
I think it would be an interesting idea to implement some card that would be the evolution of the "Big Cock" that needs pink hearts, maybe one of Debbie masturbating. Maybe increase the amount of pink hearts that she receives, but that needs her to be already horny, in other words, a quantity of pink hearts, then the evolution could be to reduce that amount or even take the need, replacing the "Big Cock ".
Debbie's idea of giving the video recordings as a gift to someone is also pretty cool, but I think it would be a big jump for her to be comfortable with it, and from the author's description, he wants it to look as natural as possible.
Regarding card tactics, in the previous version and in this new version I ended up not feeling the need to use the "Hold Head", I even researched this card in the previous version, not yet in the current version.
From the description "Hold head" seems to be an improved version of "Cup Balls" that gives you 3 points for blue hearts, but that costs 1 pink heart and with the "Tight Grip" upgrade you would not spend a pink heart "
The "Cup Balls" you get 2 points for the blue hearts and with the "Massage" upgrade you get 3 points for the blue hearts, as described the two would be the same, then it would be the choice of each person which is more pleasant to see.
I didn't get to see that in the amount of pink hearts that this has been generating for "Hold Head", but for "Cup Balls" in more advanced turns, when Debbie is almost cumming, she gets a lot of points to fill her pink hearts. .
There are some events that you get the evolutions for free, the ones I managed to activate were "Tanktop", and the alien metal to make the food printer. The first costs 1 CR and the other 3 CR.
I think it would be interesting to continue with the history events that give cards, but perhaps give the necessary CR to the player who has already done the research, or leave these cards blocked for history events, so he doesn't spend these points "for nothing".
In the second case, the story makes it very clear that it is an option to choose to exchange confidence for the 3 CR, in a point where confidence is generally low, so I think there are some reasons, but in the case of the "Tanktop" I did not see a decision interesting like that, so maybe leaving this card locked would be cool.
Finally, I think it would be interesting to make a quantity of CR available after we finish with the current version history to be able to test all the cards, because the progression / time curve takes a long time.
I found a beautiful work by the author of the game OnEdge and the artist ScarlettAnn, I hope they continue with the partnership, I can't wait for the next versions, the scenes of Debbie cumming alone and together with the person she is milking, and several others.
That is why I felt like writing these possible recommendations.
Congratulations to the Team.
