Thank you so much for taking the time to write down your detailed feedback and suggestions!
You are definitely hitting a point with the game being very overwhelming right from the start, it has been one of the weak points early on.
I really like your idea to add some dedicated trainings that can be used to learn and optimize certain obstacles in the game (or the movement in general), we will have a look into that!
The main hall training ground (or at least any option to play around with a ball outside of the actual run) was actually on our todo for some time and got cut out of the scope because we were not sure if it is really needed. I guess we put it back on the menu :)
Thanks again for helping us steer the game in the right direction, let's see what we can do!
