Hey there!
First, Epic - I am speechless by the daring move you made - making this awesome engine’s source available to all (subscribers). I think I lack the words to properly describe how thrilled I am by this - but someone probably described it already
Secondly - Are you planning to release any of the older engine’s sources (1, 2, 2.x, 3)- just for curiosity’s sake?
Thank you and do keep on this awesome work!!
