BD got tooo fixated in making Basketball interesting (we all know he used it as an excuse to delay even more, though). If he's not that good he could have done what one of the VNs I follow and that is in my signature did: Just don't make it a minigame, make the basketball a still and not an animation, if it really bothers you that it's too easy, put a couple of choices there that determine whether or not you'll win the match, but focus on what is important, the 'story'.
Also, due to his bad history with delivering things on time, lying and setting deadlines and polls that he later ignores, reworking ANYTHING was a really bad idea. Again, the only dev I forgave for doing this is the same dev whose VN I have in my signature. He's a victim of his own perfectionism and he can't help himself, but at least he actually delivers on time, delivered a high quality remake and he has never blatantly lied and made empty promises.
Due to his terrible history BD should have completed the VN and then focus on 'reworking', but that's too much to ask.
No one asked BD to make the game of the century in regards to writing, great renders or even decently attractive models, all he had to do was working, keeping his mouth shut, delivering on time and actually hiring somebody who would monitor that he actually worked, but the fact that he couldn't do at least one of these things is frustrating, especially when many 'new players' ignore what's going on and they blindly throw money at him while he fails to do what he's being paid for.
