Got it for free off PS Plus, about an hour or 2 in. The fundamental mechanics are really janky and the serving is terrible.
Sometimes your player will jolt over to return and other times they wont, the returns are really jolty too.
The serving tutorial is garbage, doesnt teach you anything outside of sometimes hitting it in. Then when you actually play you will spend ages trying to figure out how to avoid getting punished with an instant winner on every serve.
The game is poorly taught, theres a steep learning curve and very little direction. The character models are really creepy to look at.
You literally cannot beat the top players even on very easy mode. Your player doesnt react when its right at them or within arms reach.
Smash Court Tennis 2 is considerably better and its Ps2. The devs of this game maybe should just call it a day as they are clueless.... an absolute disgrace
