Exercise for the mind and thumbs!

Great game!

This game will surely test your multi-tasking skills! Colors and graphics are basic but exactly as needed as they should not distract from task in hand. The premise is simple; make sure your blocks jumps over the hole. Sounds simple, but it's not! On each track the holes show up at different times so you constantly need to be checking each track. Been playing for a few hours and this game clearly demonstrates why people should not text and drive!

Enjoyable and challenging, I recommend Duality!
