Well, if it's any consolation it's technically not the "last" day, just the end of the Jam-release of the game (hence why I called the game a "glorified demo"). I did plan to have Shion (and a few more actual Touhou characters) but I ran out of artistic motivation towards the end of the jam period. When (if) I get around to making a day 4 and beyond, hopefully Tenshi will finally get a match. Though it'll still probably be with Shion.
