• The speed of your ship actually depends on your altitude. The lower you are to the ground, the faster you go.

• Your speed at maximum throttle is approximately 4 times higher than your speed at minimum throttle.

• Afterburner triples your speed. Each afterburner pickup gives you 120 units, and you use 6 units per second, so each pickup gives you 20 seconds of boost. It would take you 60 seconds to travel the same distance without afterburner, so each afterburner pickup saves 40 seconds!

Weapons can be fired rapidly if the fire button is held down, however, you can mash the fire button every other frame to fire much faster!

[1] Only in the data for 9-1. The object doesn't appear anywhere on the map but may spawn in tunnels. It's some kind of flying enemy.

If a tunnel is part of the list of objectives, you can go straight to it to skip any previous objectives.

There is an optional tunnel in 1-2 that contains 9 afterburner bonuses and regenerates each time you enter it. It's worth traveling through this several times to gather enough afterburner for the entire run.

Here is a collection of maps with the intended order of events and relevant powerups marked. (Done, may add more items of interest if needed)
