Character Selection. Choose Rosa. She can destroy enemies before they can spit out anything threatening.
Stage Order. This is what I used:
- B-1 Lv. 1 (Forest)
- A-2 Lv. 1 (Graveyard)
- A-1 Lv. 3 (Harbor Town)
- B-2 Lv. 2 (Swamp)
- C-1 Lv. 2 (Lakeside)
- C-2 Lv. 3 (Volcano)
Of course, one should avoid the EX Canyon stage and go straight to the castle. The Canyon's there for maniacs. :)
Bomb Distribution. Admittedly, I panic-bombed throughout the final stage, but I do remember areas that I would usually bomb:
- Stage A-1 boss: the third big Deathscythe that creates rings of scythe blades.
- Stage C-1 boss: columns of cubes quickly moving from left to right.
- Final stage: the third and fourth Deathscythes
- Final stage: the two large red Cyclopes
Power Up Distribution. There are only two critical areas. The first Power Up should be saved for stage C-2 with the large boulder in the middle of the stage. It spews rocks everywhere, but if Power Up is used at this point, then the player can pass through them and focus on the enemies. It's also a good way to get the extends from breaking 20 million and maybe even 45 million.
The second Power Up should be saved for Jitterbug. Use it right when the battle starts to kill him as quickly as possible.
Usage of the Auto-fire. Though not necessary, it is very helpful in killing anything quickly. On the Xbox 360 version, there are two additional auto-fire buttons for shooting. One can hold down, say, the auto-fire left button and tap the fire left button to make Rosa's option shoot both its usual shot and semi-homing roses almost simultaneously. I don't know if this is how auto-fire is supposed to be used, though...
What to do after this? Try clearing the game with all of the stages played at level 3. Death Mode isn't troublesome until the final stage, but after that, it's a nightmare. On one play-through I've lost all five of my lives there -- how embarrassing...
Anyway, I hope this gives you a general idea on how to clear Deathsmiles easily. I was amazed that these little bits of knowledge allowed me to clear the game on my third play-through (though I'm a tiny bit disappointed that I couldn't do it in one!). If you need some help on particular parts of the game, we can discuss that here.
