I will build a playable unity prototype of your game


About this gig
Please message me before ordering so I can review your idea and recommend the right package, or send you a custom offer.
Have a game idea and need to know if it's fun? I build playable Unity prototypes and vertical slices, with code structured to grow into the full game instead of being thrown away. I'm a Unity/C# gameplay programmer with 3 years at a game studio on commercial titles, plus 20+ freelance projects delivered.
What you get:
- A playable build you can test and share
- Clean, modular C# that's yours, in your repo or as a Unity project
- A playable build at each milestone, so you see progress early
- Notes on what to build next
How it works:
1. You describe the idea or send a design doc
2. I confirm scope, price and timeline, split into milestones
3. You play the builds as I go and send feedback
4. Final delivery: source, build and notes
I enjoy roguelites, action, arcade and RPG systems most, but I'm happy to look at any genre.

FAQ
Do you make the art?
For prototypes I use placeholder or asset-store art. For a vertical slice I integrate your art or we pick asset packs together.
What do I need to send you?
A short description of the core mechanic and the feel you want. A design doc or reference games help but aren't required.
Can the prototype become the full game?
Yes. I structure the code so it can be extended rather than rewritten.
How do we communicate?
In writing, through the Fiverr chat. You get short updates and a playable build at each milestone.
Can you build the full game after the prototype?
Yes. I send a custom offer split into milestones once we know what the game needs.
