I got passed the cactus on level 3, then got hit.
Best way (if not gotten to 4th level) balance shooting tanks and procceeding,
I got like 10ks for each level, instead of 3-5ks. Really anything over 17ks by level 3 is taking down "extra" tanks. Which isn't easy in it's own right...
The scoring system in this game stinks, like in Up 'n Down.
Wish it was more like Jungle Hunt rewarding a large increase at the end of the level... not just some small 1 to 4ks bonus points.
Yeah, this is a terrible game for the high score challenge because of the terrible scoring system. I feel like I'm cheating if I take my time, lol.
