OK, I really like the premise of this game, and I think it has potential, but the execution is highly flawed.
First of all, the Unity engine is bad. Unity doesn't even allow you to scroll the text backwards if you accidentally advance it too early, and saving your game is weird. You should use Renpy instead. Renpy doesn't have those problems. I gave up on the game when I attempted to save, failed, and lost about 14 days of progress. If this was a Renpy game, I wouldn't have had that problem. But anyway...
Second, the art isn't very good. The succubus character isn't even sexy. I love the idea of the financial domination inherent in this game, but a financial dominatrix has to be, you know, sexy, or else it just doesn't work. And while 2D art can be sexy, it is possible, it would be much better if you just used realistic 3D renders.
Thirdly, the handjob interface is just weird. It's not very clear what you're supposed to do or how. I would either make that a lot more clear or just completely reimagine how those scenes play out.
Fourthly, there just aren't enough things to do. If you want to make 90+ percent of the game in this single room, that's fine, but you should make more things happen in the room. More interactions with the female character, more FemDom scenes, more bondage and discipline, more humiliation, more cuckolding, lots of options. Not just "we went to the park," "we saw a movie," etc. Will that stuff be coming in future updates? If not, I can help you with some ideas...
But anyway, I'll be keeping an eye on this game, because the premise and some of the writing is really good, and there just aren't enough games that focus on FinDom. Thank you.
