The game is really fun, I like the music and sfx , but can you add a sort of arrow to show where the bullet is  since its difficult to catch it back when it get out of screen bounds

This is a lot of fun, I have to say. It can feel a little unfair rather than more difficult as the level progresses and enemies spawn far apart, especially because the bullet can go off-screen (which is, as Robin said, a bit iffy to deal with), but I still had a great time with this!

Cool! But I felt the aiming was a bit weird. Also, a great addition would've been some sort of indication of the bullets position when it flew off screen. As of now, it was almost impossible to catch it. It was fun when you got the hang of it! :D

Good game, has good art, sound, an interesting idea and some nice gameplay to it. 

Loved it.
