The game started out like a really good horror game with plenty of chills down my spine like with outlast. However, a few levels in, where the versions on other platforms give you reasonable amounts of gas masks, the switch version gets you like a minute or two per the 1-2 obtainable gas masks per level. Eventually in the final levels library, D6, and tower, the whole game becomes like the movie Ender's Game; where you'd have to keep restarting the level to do everything like a perfect pro speed run or you'll die of running out of air. This was all in normal mode, which is the easiest mode. Going over YouTube walkthroughs isn't too much help because in the last levels, the switch version cuts out essential sections available in the versions on other platforms where you have the chance to get additional gas masks. The switch port neglected to do proper QA after the first few levels and made this otherwise really good game suck when actually trying to finish it. The constant dying becomes very boring.
