“The pixel character and asset pack tools let me test combat feel before hiring an artist. The style was consistent enough for a vertical slice.”
Jordan Park
2D RPG prototype

“HD portraits with transparent backgrounds dropped straight into Ren'Py. We iterated on character designs in hours instead of weeks.”
