I finally had time to try out 1.3! Here's my thoughts:
Wisper is really good! I thought for sure I wouldn't like them, but they turned out to be great. I like their personality and writing a lot! Also Wisper's color scheme is amazing! Wisper's spiral set to 13 speed with the Spiral event is, no exaggeration, the most mesmerizing thing I've ever seen.
The new voices though, I'm really not crazy about. It'd be nice to have an option to switch back to the old ones, since the new ones are so weird and distracting.
My biggest request though would be a way to display the visuals from the spiral or yo-yo event all the time. I wish I could just stare at Sal's Yo-Yo or the Spiral Event (especially mixed with Wisper's spiral) endlessly without having to wait and re-trigger the event over and over, which really breaks my immersion.
Overall, another great update! I'm waiting eagerly for the next one!
