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.
YMMV: Time Fcuk
Awesome Art: For an incredibly low count of colors, the art does a great job of portraying the game.
Difficulty Spike: The levels in Chapter 2 are much harder than anything in the game proper; While the first levels could be solved at ones own pace, these levels require good twitch skill.
Ear Worm - The story mode's very catchy— and very lonely —background music. It starts off as a repeating series of beeps, and becomes a song about half way through the game.
