Port 3, Graveyard 3, Forest 2, Swamp 2, Lakeside 3, Volcano 3 This gets you 3 1/2 lives (1/2 in swamp, 1 in Volcano, 2 from Score), without activating Death Mode.

I used the following order: lv1 forest, graveyard. lv2 lake shore, swamp. Lv3 port town volcano. Then the last level (no canyon). The first extend comes in the volcano stage. You go in with 1000 points, all powered up. Before the second stones from the left i start power up mode. Then you laser the stones and enemies until power up mode runs out. The next extend comes in the last level. Power up mode and then letting loose. It helps for jitterbug when you can begin the battle with power up mode as he goes down faster. When you can begin the last fight with 3 lives and all bombs, you can nuke the last boss safely.
