Vector Lantern

Collect both lanterns before docking at the exit. Thrust coasts until a wall; open edges are fatal. Arm a brake to stop after one cell, spending one of three charges. Use your 12 fuel to reach the off-route lantern and return safely. Toggle brake again to disarm.

Arrow keys or thrust buttons move. B arms or disarms one-cell braking. Watch the board edges: coasting into space ends the mission. R relaunches. No reflex timer.

One handcrafted inertial navigation room, not the source campaign.
