Before everything else, I think this one has one of the cutest visuals in the jam.
Having said that, tho, the actual gameplay is painly frustrating. I don't think the key layout is the problem but rather the fact the UI shows two horizontal lines that go in opposite directions, which really makes everything harder than it should. I guess if, instead, there were two vertical bars that go from up to down it would be way less distracting. As of now, having to asimilate the color of the mochi, the key that corresponds to it, the hand that you have to use to that, the correct timing, all while focusing in two diff points at the same time is not so fun. Even less when that is supposedly the easy difficulty. Maybe girls have a better chance to this but I'm a simple man, my brain doesn't go multitasking.
At the end, with all the distractions, I can't enjoy the music which is ultimately, in my consideration, the whole point of a rhythm game. Nice looking effort, tho. The story also gave me some silly chuckles.
