Lovely game! I love the mood I love the pace.
It needs to be said that people will be reminded of sonic and his homing attack, but I like the way you handle that rhythm that encourages methotical but fast plays rather than button mashing. Some may have to memorize the right patterns to S Rank (like myself) but I think you got a real gem on your way if the later levels can ramp up the difficulty with this rhythm.
No real complaints, although you get a lot turnips so far. I feel like things will have to be super costly for them to be worth something.
