not bad
Good:
1. Graphics
2. Atmosphere
3. Difficulty
4. Auto-reload
Bad:
1. No bosses
2. Repetitive enemies
3. No high-score table, so what's the point of a score?
Ugly:
1. The rifle was worse than the shotgun, later weapons shouldn't be worse than earlier weapons
2. Why would I, with two melee enemies charging at me, be standing in place with my ranged weapon instead of backing up?
3. enemy AI very low
