An update for local multiplayer (up to 4 players), plus more arenas would be fantastic. In fact, why not add a level editor to create your own arenas. Also, new ball types (ie extra bouncy etc), and a Quick Match mode (with varying AI difficulty). 

One of the finest on the App Store, and for 59p it’s a no-brainer!

Make holes with different points like 10
If i collect some points, where can it pay for new balls,extras magnetic effects or else.
Make a better Snooker Effect, if a shot not good for the extra dry
It is better to win by points or balls
The wheel, ok 4 nice extras to make a better effect for the game.
a magnetic effect rolls balls in a area to the nice smilies in, and if they laught, better points as the angry one.
The black ball, dont touch it, or you lose
Double strike or a free ball placement
Make a nice extra level like a minigolf snooker ball
O.K.
