Survive the robot rooms. Walls electrocute on touch — you and the robots both.

Controls

• Arrows — move (8 directions)
• WASD — fire. Single keys shoot the four cardinals; hold two keys at once for diagonals (e.g. W+D shoots northeast). You stand still while firing.
• Or pick the numpad control scheme in Settings: 4 6 8 2 for cardinals, 7 9 1 3 for diagonals — one key per direction.
• To chase a robot to the northeast while strafing west: hold ← + W + D. Movement reads only the arrow keys; firing reads only WASD/numpad — they do not interfere.
• Esc — pause
• F1 — announce score
• F2 — announce lives
• F3 — announce room
• F4 — announce robots remaining

Tips

• Touching any wall is fatal. Robots are dumb — nudge them into walls.
• Killing every robot does not auto-advance. You still have to walk out through one of the four exits in the perimeter wall. Clear the room first and you collect a bonus (10 points per robot) plus a fanfare on the way out; bail early and Evil Otto enters the next room with you. F4 confirms how many robots remain.
• Linger too long and Evil Otto arrives, bouncing on a tritone. He cannot be killed. He passes through walls. Run.
• Once the room is cleared, each of the four exits sings its own chord pad. North is bright and high; east is mid and stable; south is warm and low; west is deep and dim. Walk toward the chord you want — louder and more central means you're closer.
