I Made a Full Game’s Art Assets with AI in 3 Days — Here’s How

As an indie developer, I used Midjourney, Leonardo AI, and Krita to create character sprites, backgrounds, and UI icons in just three days, saving thousands on outsourcing. Here’s my workflow and lessons learned.

Background: Solo Dev, No Budget for an Artist

I work a day job and do indie game development on the side. Last time I commissioned a set of character sprites, they wanted $500—too much. For my new project, I decided to go all‑in with AI and see if I could pull it off.

Step 1: Midjourney for Character Concepts

I subscribed to Midjourney’s Standard plan and used the --sref parameter to lock in a consistent style. Half a day and about 50 generations later, I had 6 character concept drafts that fit my game’s world. I tried Leonardo AI, but style consistency was harder to control.

Step 2: Leonardo AI for Backgrounds & UI Icons

Leonardo’s free tokens were plenty for generating backgrounds (forests, castles, caves) and UI icons. Their model library includes a pixel‑art model that was perfect for my retro‑RPG style. I used the “Outpaint” feature in AI Canvas to upscale images to 1024x1024 without spending extra credits.

Step 3: Krita for Touch‑Ups & Composition

AI‑generated characters sometimes have messed‑up fingers or asymmetrical details. Krita’s free brush engine let me fix those quickly, and it can edit PSD files directly. I also used it to create facial expression variations (happy, angry, sad) — still faster than drawing from scratch.

What I Learned (The Hard Way)

  • Style consistency: I had to settle on fixed --sref and --stylize values after some messy early attempts.
  • Layer separation: AI outputs flattened images; for animation you have to cut out layers manually.
  • Commercial use: Midjourney’s Standard plan allows commercial use, but check the fine print.

Honestly, AI art isn’t a replacement for a real artist, but for indie devs like me on a shoestring budget, it’s a lifesaver.

💡

If you’re using AI for game assets, definitely do some manual touch‑ups, especially on hands and faces. Otherwise players will instantly notice the AI vibe.
