Lots more work needed
This looks like a good start but there is a lot more work needed and and attention to detail is very poor. For example, this is a tennis game but you get messages saying great table tennis! There are loads of spelling mistakes. I have only been using this for a week so not sure what else is not working but from what I have seen so far, the lack of attention to detail speaks volume. Too bad better care was not taken to develop this game. Maybe checkout a tennis game or two for PSP and learn from it.
