HARD BADGE HINTS:
1. Hunt UFOs, they're worth 25k each.
2. Save health bonuses for later.
3. While jumping over ship, repeatedly slap it with tail.
4. Avoid bigger ship groups.
It's quite funny how probably 90% of effort put into this game was to create fireworks, planes, flashes and tons of other stuff which only distracts and irritates players. I like the game though, it's totally addictive. My eyes hurt ... >_<
pkripper4: it's because game increases RAM usage throughout the level. On the last lvl it eats up to 600MB RAM! My 1 GB RAM laptop has frozen when I had 2 opponents remaining.
