How to create with GameGen

Three steps from idea to downloadable asset.

  1. 1

    Describe the character and action sequence

    Describe appearance, weapon, and motion — e.g. 'dark elf assassin performs a quick three-slash combo with green poison trails' or 'giant golem charges and slams the ground with both fists'.

  2. 2

    Choose action type and visual style

    Select from attack, dash, jump, skill cast, or combat combos. Choose pixel art for retro aesthetics, cinematic HD for realistic motion, or anime for stylized action.

  3. 3

    Set clip duration

    2 seconds for quick actions and UI previews; 3 seconds for standard combat moves; 5 seconds for elaborate skill sequences and trailer-ready moments.

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.”

Alex Chen

Solo indie dev

“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.”
