+   GNOME Mines is a puzzle game where your goal is to assemble molecules from compound atoms by moving them 
on the playfield.
+   However, atoms don't just move wherever you want to move them to, they slide until they hit either a wall 
or another atom.
+  </_p>
+  <_p>
+   Try to build the molecules as fast as you can on each level to earn a higher score.
