So, i give a try , and for a first solo game, i say that's good ! I like the way you put the story, i find the presentation of characters well done. You get easily their main personnality and the diference between them is appreciable. I'm not a fan of Maggie and the way that you "progress" with her but that's for my taste. Also good job on the explanation of the story, as i play, i was more concerned by the Atlantis thing than the way to have sex...I find the format of a visual novel is a good one for this game, you follow the flow of the story with a little interaction and it suits well. It's almost like you read a comic. But the flaw i think, is that their are many character and it will be hard for developping intense , credible interaction and raise the sex tension with all of them. For example, i find the way to get the red head to fast, it's have it explanation for that but i'd rather prefer soft sex in a first attempt like with the doctor, but that's for my opinion (since is a first part, i expected multple teasing with girls and sex with them folllowing the choice in the second part).
But the game is really enjoyable and that's the principle.
