Hoops Mania

Gameplay is solid, maybe you could add some features. Like guys who try to defend and you have (a limited amount of) tools and tricks at your disposal to score anyway, e.g. a pump fake or the good ol' groin kick.
What you certainly can to is to add some moving obstacles which add to the difficulty level. This way you can also implement a vs.-mode. Maybe even a campaign where you have to score against Kobe, Lebron and all those other guys.

It's much too short for my taste, but I do like the gameplay! I enjoyed having three separate people to shoot with, and the bonuses that that allows.
