These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Audience-Alienating Premise: The idea alone is enough to scare people away from even downloading it. Hell, the concept frequently makes downloading it impossible (most antiviral software catches and deletes malware before it even hits the hard drive).
Villain Protagonist: From the game's site "Although touching aliens will cause the player to lose the game, and killing aliens awards points, the aliens will never actually fire at the player. This calls into question the player's mission, which is never explicitly stated, only hinted at through classic game mechanics. Is the player supposed to be an aggressor? Or merely an observer, traversing through a dangerous land?" Considering that the enemies are your own files and the character is the game itself, the game could be interpreted as you playing a piece of malware trying to destroy your computer.
