Program the robot to collect as many diamonds as possible within each level's symbol limit.
COMMANDS
- m or m1–m9 — move forward 1–9 cells (
m = one cell).
- l / r / b — turn left, right, or 180°.
- buf ( ... ) — define a buffer (m, m1–m9, l, r, b, and
loop inside; index from 1).
- loop idx n — run buffer idx exactly n times (n = 1–9). Loops may nest inside buffers.
- Symbol limit: each move/turn = 1, each
loop idx n = 1, each buf ( ... ) = 1 + commands inside (parentheses not counted).
SCORING
- +10 points per diamond collected
- −2 points per command symbol used
- −15 points each time the robot enters an obstacle cell
- −5 points each time the robot hits the map edge
- +20 bonus if all diamonds collected
- Leaderboard: only perfect runs (all diamonds) can be submitted
FORBIDDEN CELLS
- Entering an obstacle costs 15 points but the robot keeps moving — it does not get stuck on that cell.
- Hitting the map edge costs 5 points and that step does not move the robot.
