I really liked it!
It's a very fun, creative, and contentful game. I love to trow mines on the ground and push him into them! =). But there could be more sounds, for example, for hoses, and more radio musics. Also, the blood is VERY crappy, make it more realistic!
Here are some suggestions:
1. spears/throwing knives/bow and arrows, something that you can throw at his head and watch him bleed to death. ^^
2. more medieval weapons, swords, axes, cannons, and those sort.
3. futuristic stuff, like lightsabres and laser guns.
4. More real-person like Skin speeches, like Bush's (that one is good, the others no.).
5. More items! =p
