Yeah, needs work
The design of the monsters is probably the strongest point in this game. The thing that really made it lose points was how hard it was to shoot things. It just seemed pointless, as by the time the weapon had loaded, I had gotten used to manuevering around the enemies. The sounds were alright. I suggest you give the player a weapon that doesn't act like this or one that has a much faster timer. You can basically just shoot anywhere and hit something.
It was a bit interesting to have it be timed. The artwork could also use some work, as the graphics just looked a little silly in this. At least the timer did a fairly good job of motivating me. There could also be music as the same generic sounds with the phaser get old after awhile. What are these creatures doing in space anyway?
