My questions are mainly regarding the mechanics of the "bomb" attack. It's been a long time since I've played Gyruss, so I can't remember all the rules regarding the bomb attack.
1. Is the bomb attack able to destroy the "pod" bosses' pods even when the pods are closed (which makes them immune to normal attacks)?
If yes, then more time could have been saved in this speedrun by using 1 bomb to take out 2 pods (for the later pod bosses with more/adjacent pods) as long as there is sufficient bomb ammo.
2. Is it also possible to destroy all 3 spaceship bosses (Stage 27 at 17:20 in the video) with 1 bomb?
3. Also, I noticed that even when playing near-perfectly, the player only accumulated so little bomb ammo in total.
Is there a way to manipulate more bomb powerups spawning (at the cost of some time) in order to acquire more bomb charges to kill some of the later (more difficult) bosses more quickly (thereby saving time overall)?
