+			The goal of Hextris is to keep your stacks managed and inside the outer gray hexagon.
+			<br>
+			<br>
+			You control the rotation of the inner hexagon with your arrow keys (or by tapping the left and right sides of the screen if you're so inclined)
+			<br>
+			<br>
+			Your score is based on the amount of blocks you clear in one combo, as well as the number of consecutive combos you can achieve
+			<br>
+			<br>
+			At any time you can pause by pressing p and restart by pressing enter.
+			<br>
+			<br>
+			If you want to report a bug you can press I and send it to ___@gmail.com with the text that pops up and the issue you've encountered
