Thank you to everyone for the responses. I will be releasing a new public version shortly which will have two new animated h-scenes, as well as two of the existing h-scenes will also now be animated. I needed to find the right workflow to be able to properly implement animation in a way that I liked and I believe I have now done that. The next version won't have any specific game play changes.
That being said, I have taken on board feedback and have started tweaking the game play to allow it to flow better, as well as to make it a little less monotonous, and so that things make more sense.
For example, the gallery page will show both locked and unlocked scenes, and give some clues on how to unlock them. This way there will be less guessing as to what is needed - additionally the requirements will be a little more forgiving (e.g. 40 points in any skill instead of a specific one). Also there will be more uses for Sepith, such as purchasing upgrades that may enhance certain actions. As well as some other small changes as to how the game plays.
I've also been asked about having additional girls and the answer is that I am open to having h-scenes with other characters, provided it is done in a respectful manner towards Altina. I will need to consider how I plan on doing that.
That's all I wanted to say for now except that I do read every comment so please continue to do so.
