Those pigs
I initially thought this was going to be something really cheap or pointless, but I was quite surprised! It has most of what you could want in a "Doom" like game. I loved the little bouncy sounds you made whenever you fired the slingshot. My only complaint is that I am unable to get past the first door in the first level! I have fired and everything and nothing is happening at all! Anyway, there was a lot of detail and you gave us a large environment even if it was not as detailed as, say, "Doom".
