This is a standalone playable prototype of the hacking minigame from a larger sci-fi game currently in development. The full game will feature this mechanic as part of a broader world of exploration, hacking, and survival.

Reveal tiles to map the node grid. Clustered repeated letters mark password characters. Rarer letters come first in the password, more common letters come later.
Avoid alert nodes. Alert nodes corrupt the signal around them — clean signal only exists away from alerts. Lock in a correct letter to reset the alert meter.
