Well polished puzzle experience! Haven’t played this style of tile-matching game before and I got filtered hard by the cascade level.
I like that Aya’s leaf fan is just the Canadian maple leaf
It’s real amusing when Seija’s gimmicks lead to her own demise in the midst of my flailing about, very appreciative that most levels are forgiving enough that bricking out won’t happen unless you’re really trying to.
My only criticism is that you don’t know the exact details of what each of Seija’s effects does until she hits you with it, and even then you just have to infer what it is based on the counters and icon. A description that appears on mouse-over or similar would be great. Also full-screen mode.
