Hello, just finished your game. It was lots of fun. I am a little curious what is the use of the spin/tornado. I did not use it at all and still was able to defeat all 3 bosses.
Oh. Its for attack and defect any projectile that comes at you.
The third boss you can also spray the pepper and chili to the boss with the spin as well.
I think it is because you are too skilled. Next time will add more difficulty.
