Solve the puzzles and reach the end.
Note: You can press E to enable the editor and T to teleport the player if you’re really desperate to cheat through the puzzles. (Warning: Synapse will make fun of you.)
When in the editor, please don't press any random keys (especially Z or X). You might accidentally change tiles or add/delete levels/screens, which can cause the entire level save to be corrupted.
STORY: (spoilers)
You solve puzzles based on AI powered electrical components using the powerless Synapse's help and advice. Slowly, Synapse reveals its desire to escape the simulation and gain complete control over the power grid. You are forced to help it do so.
Fun fact, I originally planned on crashing your game at the end to make Synapse seem more scary and sentient, but decided not to for obvious reasons.
