Here's what I have so far:

The good-
Variety of weapons
Player design
Controls
Music

The bad-
Starting weapon is the only weapon I used to "beat" the game. Needs to be toned down.
The background design needs to not have the player and enemies blend or rather, hurt the eyes.
Needs more variety when it comes to enemy design
Needs big bosses
Go more in-depth the the control layout and usage of it while playing (i.e. player must move around in a boss while shooting at its' weak point(s)).
Overall UI needs a touch up.

Other than that, I really do hope to see more :)

wtf?!!!!! the description is awesome!!! but why the kong logo is present?!!! and the game is awesome too!

Pretty nice game but the flamethrower is a bit overpowered.
