Another year, another banger! The art style is very Newgrounds circa 2007, which I do mean as a compliment, because it works very well here. And of course your character design is top shelf as always. The masks are nice and varied, and they all made both visual and mechanical sense.
I got stuck on the bunnies for a hot minute, but eventually I was able to figure it out. The puzzle design is actually pretty good! I just suck at execution, haha. (I managed to get lost on the way back from the tanuki bathhouse and had to repeat that sequence...)
Love the first-person overlays as well. Nice touch.
