Yes the game could use a few tweaks. Like it would be very nice to see some type of health bar on the things you are killing. It's very hard to tell what weapons do more damage then others. I have died alot do to running out of gas mask filters. There was 1 boss fight were I had only 1min 20 sec of air from a save point to kill a boss that all so had a talking cut scene (that used air) took me 12 attempts to make every shot count and was on the brink of death to complete the level.
