This was a really nice game.
The design is cool, and i loved the take on loosing sight as the spark flickers out.
NO SPOILERS; I enjoyed the different levels and how they evolved.
The game also created space to learn the mechanics before it got to hard so i could spend majority of my time testing paths instead of getting annoyed with the controls and mechanics.
Really cool, ended up playing it more then once just to see if i could have taken different paths then i ended up doing.
