i only have one thing to say about the scenes being outdated.No, what I'm saying is if this keeps on like it has up until now, the redone scenes will look outdated in a while and he'll just redo them once again, thus artificially prolonging development. Better approach would be to finish the game content-wise and then redo older scenes once that seem subpar to the more recent ones.
work faster.
if you worked faster, you would not have the extra work of revamping outdated scenes.
