This is a winning game for me.
Music is catchy, potion mechanics is quite nice (really? cirno potion worths 8 yen? not 9??), anyway, it's a quite fun experience and I had a good time playing this on stream and being sued by IOSYS (lol), Sanae theme is the supreme challenge since its super long, maybe a little shorter might be better.
Tested on the almost highger difficulty, and I must say it's quite nice, my favourite part of the mechanic is when they drom an ingredient, and it "ALMOST" fell into the cauldron, the feeling that you ruined it and that eggplant is on perfect balance, at border of death, with the feeling of "please jesus, let it fall to the right side!", it's just that much fun xD.
Since I'm a huge fan of taiko, this seemed lovely, so, thanks for that.
Never got to make the final potion, I just played long enough but simply didn't catch it, I wonder why is a store (never minded, Tsukasa is cute), you actually can't buy anything, there should be a mechanic to mix the potions and sell them for a higher price or create the famous elixir, but yeah, I probably should know if I played this longer.
