An arrow can only leave in the direction its head points. If something blocks the path ahead, it stays put — so send the blocker out first and untangle the order. Clear the board and the level is done. 15 stages of 20 levels each, 300 in total. Every level is machine-verified as solvable at generation time, so progress comes from reading the order, not from luck. Ice that takes two taps, keys and locks, wormhole portals and blocking cells layer in as you climb. Your first mistake is only a warning — no heart lost — and undo, hints and a hammer are there when a board gets tangled. Each level is timed, so you always have your own best to beat.
Untangle the order and send every neon arrow out. 300 verified levels.
