The game is fun, but extremely difficult! It's hard to dodge bullets. Maybe the character controls could be faster or there should be some kind of a short time shield activated by a button to deflect some of the bullets. Or maybe a health bar with 3 hit points. I didn't feel 3 lives enough. It's very easy to die. I had to defeat some enemies in a cheap way.
I like the sound effects and the music, also the glow effect and parallax scrolling is nice too!
