Bug fixes.
i remember people asking when C3 was launched
"will it do 3D?"
and ashley was like
"3D is possible but will require us to change the entire structure/engine, and im afraid 3D is not going to happen"
Couple of years later
Ashley "Construct has 3D layers and 3D sprites"
... i wonder what will happen in the next 2-5 years .... ^_^ can't wait
