About the end of the third planet but once I lose one I lose them all pretty damn fast!
For some reason I sometimes cannot find out how to progress in a level and end up losing all of my time bonus though. Any tips for that, like I have no idea what triggers the enemies to spawn at the end of the levels?
Normally for the next "wave" to appear, you need to kill a certain percentage of the previous wave. Sometimes you may be short say only 1% so this means you just need to kill 1 more asteroid/rock from previous wave.
A good example to test this is Planet 1 Phase 1.
1st you get 1 big rock, then 3 smallish rocks appear, then 1 more big one. To end the level you need to have killed all the large portions of rock. Until you do this it won't trigger the little red things, which end the level. Killing the remaining small blocks won't help much, you need to zoom around the planet and find the big chunks etc. As soon as you blow the last big chunk into small pieces, the red things will appear.
Every now and then if I can't find the trigger (rare) I quickly turbo to other half of the planet and release a bomb. (you would still get a larger bonus, even though you lost a bomb, you increased your level completion time.
Reading this though, it sounds like I have studied this game!! I haven't, i just picked up on all the small things from my 100+ plays of this!!!
I really want to hit the top 200 for this, although that will be a mean feat (I think 200 millish). I also played the Planets mode and got top 200 scores in the 1st four planets. More than anything this helped me realise which waves come when and best strategies on killing types on enemies.
Incidentally, what do you do on the Planet 2 boss, when he closes his tentacles and fires missiles at you, do you kill his missiles and wait for him to open his arms and shoot him some more? You can actually go inside his enclosed tentacles and shoot him and all the missiles can;t get you as you are inside his tentacles (easily shaves 30 secs off that level).
