Loved by indie developers
“I shipped my Game Jam entry with AI-generated sprites and BGM from GameGen. Saved me at least two days of asset work.”
“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.”
“HD portraits with transparent backgrounds dropped straight into Ren'Py. We iterated on character designs in hours instead of weeks.”
