I will develop a playable unity casual or puzzle game prototype
Dan Ng.
About this gig
Test your casual or puzzle game idea with a playable Unity prototype.
I'm Dan Nguyen, a Unity developer with commercial experience since 2023. I developed Key Jam solo, including its key-lock mechanics, boosters and level tools. I also contributed to Wheelie Rider (500K+ downloads) and Dungeon Warrior (10K+ downloads).
I can turn your reference video, sketch or short design brief into:
- One focused 2D gameplay loop
- Touch or mouse controls
- Win/lose conditions and simple UI
- A small set of test levels using placeholder assets
You receive the Unity source, one agreed Android or Windows build and setup notes.
Packages test gameplay, rather than cover a complete store-ready game. Art production, multiplayer, backend services, ads, IAP and store publishing are separately quoted.
Message me with your core mechanic, reference and target platform before ordering. We will define the loop, levels and acceptance criteria before development. Revisions refine the agreed mechanic; new mechanics need extra scope.

FAQ
Can you start from a reference video or a rough idea?
Yes. Share the core mechanic, a reference video or sketches and the target platform. We will define a small, testable gameplay loop before development begins.
Is this a complete game ready for the stores?
No. These packages deliver a prototype to test gameplay. Release art, expanded content, monetization, store submission and other production requirements need a separate scope.
Will you provide art, music and animations?
The prototype uses placeholder assets or assets you supply. Custom art, music and polished animation production are not included in these packages.
Will I receive the source code, and can the prototype grow later?
Yes. You receive the Unity source and setup notes. Further development can be scoped separately after you test the prototype and decide which features to keep.
Can you add multiplayer, ads or IAP?
These features are outside the prototype packages. AdMob and Unity IAP can be quoted separately; multiplayer and other complex systems require a project-specific assessment.
