Eeh, i didn't mean it as a bad thing. Most VNs use other people's music as well, won't be a problem unless the original content owners notice and decide to take the copyright issue further.
Anyway, pretty nice game and plot for a new game, I also want to tell that the APK/Android version has an issue regarding the scene animation, starting from the scene of the Game Girl (sorry i forgot her name) when she was Flicking her Bean, the game lags badly then crashes. Is it just my device or not, I'm not very sure. Although I tried opening the APK file using RAR app to search the video content, i found them as ".ogg" format files. Usually when I do this to other games that usually their animation lag while in game, it wouldn't lag if it is opened outside the game using other media player like VLC. But your .ogg files kind of laggy and can't be played even using VLC this way. I tried restarted device, clean cache etc. game still crashes. The only animations that did play well were the HJ that jerk and MC got. So yeah I think i need to report/ask this.
Also found some typos, like "threated" instead of "threatened" and at some point you made Noel said "U" to MC instead of "you". It's small stuffs, but if you're planning to continue this good game of yours till the end, making it as neat as possible would definitely be better.
So yeah, i kinda of shut off from the game because of that crash issue above, so i don't know the content further from after the Online Game match then the girl masturbate at night. Overall nice new game with interesting plot.
