Most people have zero interest in going back a level or two just to be able to play the game.Īlso, filter time constantly gets lost when switching masks, because why would you ever retrieve the filters from the one you discarded, right? Heck, may as well just toss most of my spares onto the old busted mask, too I don't really need 15 minutes, right? Five is plenty! Wow, it must be nice to know exactly where every last filter is located so that you don't waste any time finding them.įor everyone else who hasn't played through the game multiple times and has to hunt the things down, it's more difficult, especially when you've had to backtrack and start the next level with much lower than ideal filter time.
