Thank you for such a detailed review! You don't know how relieved I am to hear you like Tirs! It was my biggest fear so far, making a protagonist so workaholic and bad at love relationships that people wouldn't like him.
I didn't touch the text speed options, in fact, so it's supposed to be the default Renpy one, but I'll take a look at it.
About the backgrounds, you are perfectly right: the office, toilets and clubs are not photomanips, but true bgs made by Oncle Mugen for the Lemmasoft Forum, but they are placeholders while Justyna makes the final bgs (like the cafeteria one). We might end using some of Mugen's (those clubs bgs are really gorgeous ), but we'll try to at least make them look closer to our style.
About the option of skipping all adult scenes... I'll think about it. I thought that perhaps people would like the chance to skip only some of the scenes, with the characters they don't like much, for example, or could change their mind and decide to see one scene in a while. I hope more people give their two cents on the question!
