It's a decent start.
This game would massively benefit from a mouse aiming system, rather than a directional based one. Having to run towards the enemy to shoot at an enemy, while nostalgic, is completely illogical and makes combat suffer from lack of decent controls, rather than actual challenge, which is never good in a game.
The graphics and art in general is fairly amateur, but will only get better as you continue to work on it, so don't worry too much about that.
The voice acting is very well done, and is where you get most of your points from me.
Overall the game needs polishing, and the controls desperately need more fine tuning. This does have a lot of potential however, and I think you should continue to run with it.
