This is a simplified version of the previous puzzle I've created. The previous puzzle was too hard as an introduction to the new constraint, so I made this simpler version. Hope you enjoy it.

Normal sudoku rules apply. Clues outside the grid indicate the smallest possible sum of X adjacent digits in that direction, where X is the first digit in that direction. For example, a row containing the digits 471938562 would have the clue 20 to the left (7+1+9+3=20), and 8 to the right (7+1=6+2=8).
