The ones in the secret sneak peek are all the green arrow one, he was just showing you can rotate them.
It all used to be so small. P.S Darnoc was the second person ever to upload a level, and was one of the first to get the game. Look at the first few pages of the forum.
Looks like some troll has had fun editing the 2.1 page on the GD wiki XD Edit - looks like I took that screenshot just in time because everything's back to normal again XD
The block limit will be 40K, but according to wiki Rubrub said on one of theese streams that there will be another block limit up to 80K, but levels that has up to 80K will have like a warning sign or something on them. And that he has fixed so dvices that lags a lot will have much less lag, maybe Ill be able to play SiriusX now xD Aaah... I remember back in the good old days when I started to play GD, in 1.6, the block limit was at 8000.
A negative for the "follow x/y" would be useful. Basically it makes the object move the opposite direction of the player in the x/y direction. This could be used to freeze objects at the end of the level when the player enters the end portal.
I'm using Fingerbang (RobTop version) for my first 2.1 level. If it doesn't get featured, RobTop needs to work on his featuring system...
