The Good

* Environmental art looks really nice.

* Controls feel smooth.

* Shooting and jumping around feels fun.

The Bad

* Character sprites are really boring.

* Projectiles disapear after travelling really short distances.

* Sound effects feel hollow and dull. Maybe make them bass-ier?

* The font you used is truly terrible and difficult to read.

* Not being able to shoot up whilst enemies are above is frustrating.

All in all good job. I had fun playing and I really enjoyed the environmental art.
