Really like the concept! I love the switching mechanics, although something I had a rough time calculating when the modes are about to switch. I felt like wanting to die when I tried passing the bullet stages for the 57th try, and the projectile dodging was so difficult (but in a good way, I wanted to prove to you that I was able to complete the game!!!!!!).
At the end I accidentally pressed the green flag on the top left of the screen and it resetted the game. Shame! I really had fun trying to beat it. Somehow you managed to create a puzzle game which is also a rage game. LOVE IT
