Hey! So let's hit the follow up points one at a time!
1) Animations. Not trying to knock it, but it just seems weaker compared to all the others I've seen. Maybe I'll pay less attention when you add the special character positions beyond Maiko's (pumped for that).
2) The notepad. I guess my only suggestion is that it's about time for an over haul. My only concern is that a lot of important information often gets stuffed into (what seems to me) like a tiny black and white text box. If you want to stick with the notepad theme (which makes sense aesthetically), then great! But, if you were to maybe increase the size of the box or add accent colors or fonts to the whole thing then the whole reading experience might be a lot more visually stimulating and rewarding. You wouldn't want it to be too distracting, but something a bit larger than what you have now just seems to make sense to me. Then again, it could just be me, and you should ignore what I'm saying. If I happen to find a good example image online or from a game I like to make myself a bit clearer then I'll PM your or something.
3) Speaking of which, ignore my tablet comments from before. On a second play through I thought everything was fine. I musta been drunk or something.
4) I guess the real crux of my sex or no sex question is will your choice have effects on the story itself (rather than just stats)? If the answer is yes, then that might also help with replayability (go ask Yummy Tiger about that, I suppose).
Again, big fan of your work. Awesome to see artists like you taking all your feedback so seriously (and releasing stuff for free).
