At first I thought that it was going to be a Harem Hotel clone (going by the description). I still gave it try, and I'm glad I did. Lovely and fun VN game. I have two suggestions/improvements for now:
1. Add the Renpy button prompts underneath the text box (like, load/save/skip etc.). Some people (me inlcuded) don't know all the shortcut keyboard prompts for these. This will make it more user friendly.
2. When viewing the stats for the girls give us a "Return to stat menu" option or "Next/Previous girl". Return just takes you back into the game, which is anoying if you want to check all the stats for the girls as you have to move back and forth for each girl. This will make it easier and more user friendly.
Keep up the good work. I will be following this game.
