I think this game had its good points. I think its weakest bit was how it was a bit too repetitive. The graphics didn't seem to do much for me either. The sound effects were fairly well done. I guess this is a pretty original game. It was hard to keep track of how many times I died. I don't even know if I did, I think I just went to the next level.
I think its biggest strength is the different variety of weapons. You didn't seem to need to collect ammo or couldn't. You just had to use everything sparingly. Putting "Ultimate" in front of everything doesn't always make it good. Well, I'm off to celebrate my birthday!
