Very charming game. Love that you can see the bullets before they come onto the playing field and how you can preview how to bullets will split in the upgrade screen, just really neat details that adds to the charm. I do think I noticed something unintentional: When you use slow-mo, some of the bullets sometimes stay slow even out of slow-mo. Also, the boss is very easy if you pick all the split upgrades and some fire rate ups. Overall was very fun.
