Really easy to use and understand, and fun to play! The endless mode was a really great touch! Makes it easy to practise!
If I were tasked with improving it I'd either switch to swipe motions or replacing the swipe graphic with a gunshot, so it's more in line with what we the player are doing (clicking a button).
Do you think Fruit Ninja was made as quickly as you made this?
