Thank you!!! For the extensive review.
Regarding the aiming facility, It's kind hidden but basically you shoot towards the opposite upsidedown side with a bit of margin of randomness. And sorry for the player being to slow, I guess I testsed it long enough to be a pro so I wasn't bothered by the speed.
Originally you could only serve when the ball hits inside the court first but then I removed it because it became contradictory with the power charge shots that are a core part of the theme.
But again thank you!!!
