You're always allowed to bump your own thread, providing there is enough updated status in it, to be worth while and I'm totally sure that changing the engine you're using and upping the size a lot is a good enough update, no sarcasm intended, or there.
Looking at the video, it would be nice if that big crater in the middle of the area had water, or lava, or some kind of filler.
Finally, will you be upping the map size any more?
I know it's a silly thing to ask, but look at minecraft and terraria, there maps just keep on going, and going. I'm sure it's infinite, but it takes up alot of space, if it gets to big.
Either way, it all looks good!
