spacing between the items of a tasks list

Question

I thought I managed to solve this by tweaking the 'after-item-skip', 'after-skip' &Co settings of the tasks package but I ran into some unexpected issues with page breaks when the number of tasks gets higher. Given I had to use some negative values, I think I didn't do it right.

Can anybody help with the proper way to solve the problem in the MWE below? I.e suggesting the right way to set the spacings (and the indentation of list items if it's not much to ask) only in 'Part 1' of the code so that the output will be more or less as the output of 'Part 2'. The spacing between the last 3 lines is fine, I just put those lines to make sure the solution doesn't break that.

\documentclass[12pt]{report}
\usepackage{exsheets}

\usepackage{tasks}

\usepackage{parskip}


\SetupExSheets{headings = empty}


\begin{document}

Answer 1

Something like this?

\documentclass{article}
\usepackage{exsheets}
\SetupExSheets{headings = empty}
\usepackage{parskip}

\settasks{
  % the next two should be set to the same value so labels are aligned to the
  % left
  label-width = 1em ,
  item-indent = 1em ,
  before-skip = -\parskip , % undo paragraph skip
  after-skip = -\parskip , % undo paragraph skip
  after-item-skip = -\parskip % undo paragraph skip
}
