So much room for improvement, but nice try
It was an ok try, but there are so many things that need to be improved before you could actually make this a good playable game.
First off, a few of the enemies dissapeared before I had a chance to shoot them, but that is an error that can be fixed. Secondly, controls dont respond to the game very well, and is quite slow reacting. The enemies have no AI, they just walk up and down like your not there, but that can be fixed with practice. Finally, there is no story to it but since its your first submission you have made a considerably good start. 3/10.
