Thank you so much for the feed back. The (R) item will reset the energy ball speed to the min speed. The energy ball will increase the speed with every touch of the paddle untill reach the max speed (values variable with the game dificulty setting). Btw the explanation for each item effect is in the tutorial. 

Thanks for the report of the ball getting stuk on the right. It is not suppossed to happen. However i detected this issue and did a script to force the ball to move away from the wall when stuk (what apparently is not working). And yes when the ball hits the paddle on the right side there is a change of direction accordingly. I will need to revisit the script when the ball is stack. Thanks again for the comment and reported issue.

The new Version is already ready to play. We have change the whole mechanism for the movement of the Energy Ball. So this should be a better and more stable. During the test run no issues where observed. I hope you can enjoy the game.
