Every time I complete a level, the game registers it as a win for both this level and the next one (both in raw completion and for rank purposes, it seems). It is bothering because since the next level is already won, I can't access the story for that level anymore. Maybe there should be a way to have the story even for already completed levels ?
 "Enigmata: Stellar War"){kind=icon}
 "Tone Matrix"){kind=icon}
 "aMaze"){kind=icon}
 "Kongai"){kind=icon}
Thanks for point this out! I just fixed this.
