Rampage jaws make it quite easy to finish. No need to ever touch the surface because you have wings and a giant mouth that kills everything around you. So mines never ever hurt you if you keep tapping the arrows to keep you flying.
The female endings were really weak.
A blind female hero, a blind female failed hero, a sex object, a woman that's out for money and someone that influences fashion. THAT's the best you could come up with?
There isn't a single game that I know that has instant death for traps such as spikes. They usually remove 1 life, but considering this game doesn't have lives but an hp bar, I think it would be more fair to remove like 1/3rd of the health bar.
Easiest way to beat the last level is to kill all the small ones first, try to kill them fast and don't let them stack up, or they will dominate the level and get all the astroids(ammo).
Just tried the game again with beetles, and the queen level is just impossible with beetles because the queen is as fast as the beetles so you can't capture more bases than the queen and you can't slow the queen down enough to save your troops from other colony AND use troops to capture new bases.
