I just completed the entire game, all story levels and score attack levels at 100%, all scrapbook and awards unlocked. As far as I know, there's nothing left for me to do, but I found this to be the best PSP mini released, possibly one of the best games I've ever played. It is a definite must purchase for anyone wondering.
The only thing I'm curious about is how to score higher, if possible. If you got any tips, I'd greatly appreciate it. My scores below.
Ah, My Magnificent Castle! Story - 2,458 SA1 - 2,344 SA2 - 7,368 SA3 - 11,754
Some Gaudy Caves Story - 2,958 SA1 - 3,690 SA2 - 7,564 SA3 - 10,464
I Claim this Waterfall! Story - 5,532 SA1 - 4,009 SA2 - 12,704 SA3 - 14,379
A Big Stupid Tree Story - 5,298 SA1 - 10,866 SA2 - 13,965 SA3 - 23,930
WHAT?! A Temple? Story - 6,939 SA1 - 10,954 SA2 - 9,279 SA3 - 21,372
I found out the answer to my question about the scoring system and I'm posting some more information for anyone interested regarding the scoring system. I contacted Mediatonic and they stated,
"The only real way to increase them any further is to hit the monster a bit later in the level, the higher your combo when you hit the monster (including the first and second hit) the more points you will bank. In some of the longer levels (such as Darkly Dreaming Duke) it's possible to leave the monster a bit later before tagging him. On the shorter levels it's generally not possible to increase the score any further if you're already at 100%."
i reccomend that hit almost every platform, hit monster asap twice and the leave him and at the top of the stage hit him for the last time(with a big combo cuz this will increase your score more)(probably)
