You're a claustrophobic triangle. You're inside a hexagon. You need to get out. Now!
Okay there isn't really a story line. I don't know why you're a triangle. But you need to escape the enclosing walls regardless, and quickly too. The levels are somewhat random in that you don't really get the exact same levels but I guess every level has its own challenge.
The game is simple in concept but very challenging. You have to master the speed of pressing left and right in perfect timing. You have to get your triangle in an opening of the enclosing walls. You have to look ahead to know where to go next. I'm telling you, it's not an easy game.
While I did not manage to complete even the first level, aptly named "hard", it's clear that once you do there are more levels to complete. I'll gander a guess this is not just one or two extra levels but I'll never see them.
(The recording volume was not quite correct and due to a configuration issue in the recording software I'm unable to fix this)
Verdict: Look, I suck at these games. My personal rating about these games does not mean it's a bad game. If you like these kinds of games you'll have your work cut out for you.
Familiarity: Tried not to play this game. Unlikely to ever pick it up again.
