The contoller works much better now, you can change your thumbstick deadzone in the controller options. The deadzone is how loose your analog stick is, setting it high will fix very loose sticks, setting it low is for newer controllers. (This also prevents the cursor flying off the screen issues)
There's now a dedicated button for using a power-up, this means you can use slow-down at all times, this was a request from a number of users.
CONTROLLER
Left Trigger - Slow down the bat,
Right Trigger - Speed-up the bat,
A Button - Slow ball,
B Button - Fast ball,
X Button - Use power-up,
Y Button - Switch power-up,
MOUSE
LMB - Slow ball,
RMB - Fast ball,
SPACE BAR - Use power-up,
Mouse Wheel - Switch power-up,
I've also fixed all bugs and memory leaks, so there shouldn't be any issues,
Any problems let me know on the forums,
Paul
