Check the pte, some small things that were negative in reviews are fixed already. Like the low quality youtube vids we get are fixed (Atleast it was 1080p in one go and I didn't see it was youtube when playing PTE).
Bit harsh?! They've made a good game, with great potential. Nothing is perfect you know. And they've stated that development will continue. They are clearly knuckling down and working hard (as evidenced by the recent PTE release).
Answering to mistakes, admits mistakes, and also means factually that mistakes were made. That is like, if I asked you if your mother knew your hair looks so stupid, and you told me no, and so I said "so your mother doesn't know, that your hair is absolutely stupid... but you aknowledge it is in fact stupid looking".
