For starters:
It’s not for starters. Tutorial gives zero advice on how to serve, and even on the lowest difficulty, the AI will hit perfect returns that are impossible to stop.
It deters anyone who is new to a tennis game to try and grind it out by starting at a low difficulty and gradually getting tougher.
The controls are janky, making you feel like you hardly have any control of the outcome of any game unless your opponent makes unforced errors.
Hardly any customization on how your character looks, and gives no further insight on how to build archetypes with your equipment.
Had high hopes for this game but overall was a huge disappointment.
