Don't be such a drama queen... he only gave 2 release dates so far, the Christmas one and by end of February, he broke the Christmas one, and simply asked for a few more days for the February date... most of the games on here are updated like that. You are crying about it like he didn't just ask for a few more days but broke into your house and killed your dog. Chill, just check back around mid-March and see what's what. There is no point in crying about every hiccup he makes at this point.
So many people are just posting here to vent their frustration non-stop, but it's really pointless, get yourselves together... He already knows he messed up, he said he messed up, continously dumping on him now isn't doing anything useful. He said he is trying to remedy the situation so give him a change to do so. Give him to mid-March and see what happens. At least now there is a solid date to work around, unlike before where the dev refused to set any release date. If he needs a week or 2 more, that doesn't really change much for people on here. I don't think there is a single dev on this forum who hasn't broken a deadline and then pushed back a release date... for about 70% of the devs on here it's their routine with each update if there ever even is one.
