Use the runway near the top right door to jump towards the top left bomb blocks and break them using the blue speed from SpeedBooster. This can be done using the full runway, with a one-tap shortcharge, where the tap is at the top of the lowest slope, and the jump is at the top of the last slope. Alternatively, a controlled release of the jump button works in place of the shortcharge, where the bottom of the thick dark line in the background at the top of the room works as a visual cue. Aiming down before hitting the wall can help make the jump slightly less precise. Use a flash suit to get through the remaining blocks.
