Hello .
Spartan has been Greenlit! 
I wanted to share good news with you more than a week ago but i was so busy working with Unreal and Creature that i lost track of time… Unbelievable!
I helped guys over Kestrel Moon to make it usable with unreal and paper2D (specifically) and results are simply jaw dropping. Finally we can use one Png for a million animations. Wait till you see it in motion inside our game!
Today i started playing around with sprite merging and i discovered a few bugs that you need to know. If you have a number of sprites within a layer and you try to merge them, then system freaks out and either disappears half of them or/and places a few ones on top of other.
It also removes newly created sprite (merged) from that layer.
And if for any reason you want to break them apart because it does not store anywhere original Z order number, you have to redo everything from scratch.
And it should also auto insert Z order value from individual sprites as long as they do not have multiple values of course.
I believe that it is finally time for you to give us a proper 2D layer option that locks sprites so we cannot move them around accidentally. current workaround that i am using is so limited and time consuming that sometimes is more trouble than good but it is nearly impossible to create a 2d game without some sort of toggling on/off layers so i have to use it. For example you can insert same sprite in as many layers as you want (some times it happens by mistake) and good luck if you want to make it invisible. You need to search all available layers, remove it from there and then add it to one you want.
Small but time consuming annoyances nevertheless.
Thanks!
