But I did finally beat Churchmouse Streets on Hard, marking the last singular Hard stage I had left to clear!
Although given beating both Matti and Avy involved builds with boosted max HP or crazy movement speed, I can't say I've really mastered them at all. But I still feel good about it.
Ancient: beat Shira on the first run I got there
Dancer: uhhhhhhhhh let's not talk about it
I don't know how I had it so easy on Ancient Rabbit, though the 7 HP probably helped even if I didn't need all of it by the end. It got me all confident in my skill, especially if I swapped to a class I've considered much easier to use, and look where that got me!
The irony in Dancer taking me so much longer is it's what I first beat all the Hard bosses with for the class unlocks. Maybe this says something about how well I play in the short vs. long term, but it doesn't matter now that I've won! (Right?)
I'm not sure which one's next after this. Maybe Defender? Bruiser? ...Or maybe I should finally try multiplayer lobbies.
