The game has a 2d Zelda gameplay feeling but with a different vibe. You and a few NPCs are "robots" that have encountered a virus that turns them rogue after some number of real-life hours have passed while playing the game.
The game does amazing at creating an atmosphere of: I need to complete the game fast before anyone turns rogue. Let me go back from time to time to give some temporary medicine to slow down their corruption. It made me so emotionally invested in saving them.
