Honestly, I didn't find this game to be that bad. I guess it's because most of the other games aren't even working for me right now. It was kind of creative. There were a pretty wide variety of enemies. Then again, I still didn't like it because it was too simple. It got annoying having to shoot everything over and over again.
The sounds were fine. You could have had better graphics. It's always nice when people put a lot of effort into this. The music wasn't bad. It was just nothing memorable.
