title: What sprite size should I use for 2D game?
body: <p>I try to create a 2D game for Android. It looks like <strong>Cut the rope</strong> (it isn't a clone but it have same level representation) if it has a value.<br>
  My problem that I can't understand that optimal sprite sizes I should use. I.e. what target screen resolution should I use to sprites didn't have anomalies on HD-devices (like Samsung Galaxy S7 and etc., phones and tablets)?  </p>
  
  <p>To make my question is clearer I ask about this <strong>1 unit = X pixels</strong> for xxhdpi-screens. What is <strong>X</strong>?  </p>
  
  <p><strong>P.S.</strong> Sorry if it's off-topic I will be grateful for link on the correct community then and if it's a duplicate I will be grateful for link on this post cuz I couldn't find it.</p>
