New low: I just game over'd
twice on HRtP, Stage 18 Hell (Jigoku) Route. No turrets there. Which means the difficulty is the same for Easy / Normal / Hard.
@'nut: for HRtP, I'm still inclined to say that Heaven is easier than Hell, even on Hard.
EDIT: 2cc Heaven / Makai Route, game over'd to Sariel once (first time through again; 5 bombs in stock, many wasted as well), then defeated Sariel with the base resources.

On another note; this.

Don't mind the purple-ness of it (emulation), but note what's in the background. Never noticed it before...
EDIT 2: I seem to be getting better already. 1 death, no bomb clear of Mima.
I fly! Soar to newer heights!

...unfortunately, I didn't record. ++Embarrassment for me.
