Castle Heterodyne isn’t just a setting — it reacts, shifts, and resists you. As Agatha, you explore interconnected rooms filled with traps, secrets, and mechanical hazards. The fortress itself feels like an unpredictable character standing between you and control.

Use Agatha’s brilliance to repair and activate strange devices scattered throughout the castle. Gadgets aren’t cosmetic — they unlock traversal options, solve environmental puzzles, and open new areas. Progress is driven by invention.

Face off against hostile constructs, malfunctioning machines, and castle guardians in real-time combat. Fights require timing and positioning while navigating tight platforming spaces. Precision matters as much as power.
