I don't care how grand the update is, that has nothing to do with making false statements. If you want more time to work on the product don't set dates.As compared to other companies who would rather bundle this as DLC and make you pay for it? Hey, be glad it's free. They aren't dragging their feet. If you want something that's breaky even in updates, I'll point you to the heinous pit that is steam direct...
Sorry that you're not patient enough like most of us.
They rather have a grand update that won't break in your face than to rush on timetables. This is an independent studio. If you want rushed products, look at major publishers instead.
