Gotta say, you have all the elements of a great game. The visuals are very good. The Story is a whole lot of fun. And the dialogue mixes well with the visuals to bring the story together. While there are a LOT of lewd scenes, it is easy to see the author is a storyteller. As a first attempt. This one is pretty great. The dialogue could stand to be cleaned up for the English translation, but as gremmie said below, it isn't hard to understand. The biggest thing I noticed in the dialogue is that phrases made in the authors original language don't translate to how a native English speaker would talk. But it is still good enough that the main point comes across. I would suggest maybe working with a native English speaker to get the English translation dialed in. I'm sure any fan of this work would like to help.
Overall very well done. I am enjoying this AVN very much.
