If interested in a PDF copy of the score table for Doukutsu Randamu on how you earn points here it is. Now with pictures of items and enemies.
I did a lot of work using two calculators, getting current score and the changed score after collecting an item or defeating an enemy. Then subtracting the new score using previous score to know the difference, to get the actual points earned. Did all of this on Basic difficulty, then the higher ones. Adding the percent to the points earned can sometimes yield decimals but found out the game rounds down to the integer. Example: 15 + 25% = 18.75 but the game counts it as just 18.
