I think it's a pretty good game and pretty good start. A bit different from the theme. But, overall it's good. The audio effect can be added for animations of walking and background music. Also please turn off the collider or destroy the enemy somehow after they are killed. Because it's really frustrating when the bullet doesn't hit the other enemy because the dead enemy is in the way and the bullet doesn't pass through it. I mean that's my suggestion mate. Overall good game. Loved it.
