Not enough filters in game
Overlooking the blase feel of the game was easy because that seems to have become the norm in video games. So what was the straw that broke the game for me? There are not enough filters to explore the game enjoyably... only to rush through... and you CAN"T BUY THEM! A game hint says to search for new air filters when you run low... Great! Nothing like spending 2 1/2 minutes to search for 3 minutes worth of air. If you run out of filters, guess what--you're f****d. You'll have to play at least one, maybe several chapters over until you eek through... simultaneously boring and aggravating.
