This game was my predicted winner of IFComp 2015. This game is well-written, has great pacing (especially in the first half), a strong narrative voice, and excellent graphics. It is easy enough for people to get into with little IF experience, but provides enough of a challenge later on to be interesting.
You play a teenage girl whose town is overrun by the eponymous Brain Guzzlers. You have a cast of creatively-described friends and acquaintances who help you out. Conversation is menu-based, which allows Cherrywell to express the real flavor of the PC's world (with a lot of 'Jeepers!').
The game has some very creative puzzles, and some more straightforward. Each character of the game (besides yourself) comes with one or more high-quality graphics that show up when talking to them.
Game play is 2-3 hours long, I estimate. I recommend this to everyone; I feel like it will be played for years to come.
