To play, you use space to select on the menu screen. The game does include a tutorial. C to jump, X to blackout, and Z to flip breakers. I will admit, the first breaker puzzle was very frustrating since it is very easy to lose your place in the dark and very easy to die, which resets your progress. The game feels very precise at some spots, requiring pixel perfect jumps it seems. I do like the choice of music. Perhaps i will try this again when i have more time to do so. It does look interesting.
