Your ammo clip is too small, the first semi-automatic American weapon had 5 bullets in it, that was in World War 2. The Doom series takes place in 2300's, need larger clip, more health, and faster turning, and maybe explosive barrels.
Just so you know, you need a recent Flash player downloaded on your computer to work well, luckily my laptop has state of the art flash and art stuff so it runs at the speed of light. 5/5
I like it a lot. Unlike everyone else I liked more then the original because you don't need to worry about staying warm (which is the main reason i kept dying, i am horrible at point and click adventure games)
It's like the first level of doom but put into a cheesy RPG form. Didn't like it that much because a lot of colors on the walls and enemies were stolen out of the game.
Cheats:
Ghost (No clipping): idclip
All Weapons: idkfa
Invincible: iddqd
Chainsaw: idchopper
(Type these in while playing the game for them to come into effect)
Not bad, a few things I would change though (just tiny minor things). Really fun to play after watching Happy Feet (dear God I hate that movie). Reminds of Staggy the Boyscout Slayer, except you use guns not swords and chainsaws.
