Next Update 1.1  ???

Hi All, 

Looking to add one more layer,  this will give you the possibility to add  a Bezel /CRT overlay in foreground (Layer1)  and Scanlines in Background (Layer 2)   

Who is interested in ?


thank you, it's very useful for all pixel arts games, the render is very pretty !

Long road to S4W !
