Mankind’s oldest enemy, the decimal numbers 1 to 5 have launched another audacious attack and it’s up to you to stop them. They have one weakness – they self destruct when they are combined to make the number ten. Select numbers with the stylus and make tens to save the world.

How to play:
– Numbers have to be on the same horizontal line and add up to 10.
– All hope is lost when the numbers break through the top of the screen.

Changes:

Just a very small update to add support for exit to menu
