Reine update was pretty great, even if the 'Level 0 friendship' event left me a little rattled lol :P Cannot WAIT to see what you've got in store for her next, esp. if that something is the barefoot version of her fight >:]]] Guests are looking to be really really good too!!
As I've replayed this game (and believe me, I've been replaying it lol, I love it sm), I've been thinking of a couple things that might be nice to implement in the future, if you decide they're worth adding:
1) A cheat/button/etc to immediately increase the difficulty by a stage (admittedly mostly so we can see the beauty that is Fabienne's grinding animation + whatever goodness you have planned for Arconte and other future Beasties). This could also be done by implementing some kind of standard 'high difficulty mode' where it starts out harder
2) If you feel like there's too little upgrades, or wanna switch them around a bit cuz you think one or two of them are a little strong, it might be nice to have one that increases the spawn rate of collectibles. The only trouble I could see with this is that, beyond a certain point, it's kind of OP--just lets you get friendship shinies quicker. This could be lessened by just not including friendship shinies into the 'increased spawn rate' bit, or it could be at the expense of ramping up the difficulty quicker :]
