YMMV / Lifeless Planet

• Ending Fatigue: After most of the mysteries are solved and the most difficult levels played through, the game drags on for quite a long time.
• Nightmare Fuel: The Abandoned Atmosphere? The Vivid Hallucinations? The idea that your character is stranded, alone, with his entire crew dead with only a empty planet to explore? Yep.
• That One Achievement: 'Survivalist', for beating the entire game without dying. It's not a very long game, but it's very, very easy to die in an instant, forcing a total restart, especially with the rather floaty jumping controls. Only 1.8% of players have it on Steam.
