There are four difficulty levels: hard (Hexagon); harder (Hexagoner), and hardest (Hexagonest). ‘Hyper’ level is unlocked by surviving for over sixty seconds on a level.
The game is based on a prototype which Cavanagh created for a twelve-hour game jam in early 2012.
If you can’t get past the first 5 seconds, you can always listen to Chipzel’s fabulous chiptune soundtrack online!
