hey dude its Gogs from gamestone, im going to make a run at your salamander score, might try the gradius 3 one sometime but that bugger is hard and i aint played it for years.
For me, what works is that the strategies are very situation specific. It really makes a difference to know what's coming ahead so I can use or save the resources - aka weapons. But one thing that is generally a safer idea is to jump and kick instead of comboing. Also, finishing an enemy as fast as possible before more enemies arrive is good.
About the scoring, I thought that the least lives you lose, the more enemies appear (so you get more points). You proved that wrong then.
Haha congrats on Battle Toads! I don't know what you guys do to get more points on each level, but my goal is going to be beating lvl 3. I don't think I'll ever do it though!
