Game development: playable builds, actually shipped
ReactivVibeAI Studio — the software side of ReactivVibeAI. We build browser games that run — and the strongest evidence of that is Reactive Rhythm, a rhythm game we designed, built and shipped on this domain. You can play it right now, in your browser, without installing anything.
| What you buy | Price (USD) | Turnaround | Revision rounds |
|---|---|---|---|
| Game build — one developer, 80 hours | $16,500 | 30 days (playable build in 14) | 2 per milestone |
| Game build — team, 160 hours | $29,500 | 45 days (playable build in 14) | 2 per milestone |
| Change orders, beyond the agreed hours | $115 / hour | Quoted per order | n/a |
Games are priced the same way our applications are: a fixed figure against a stated hour count. What moves it is systems, not art — leaderboards, accounts, save state and payments each add hours. Art and audio scope is quoted separately from your brief.
What ships
- A playable build that runs in the browser on desktop and mobile, no install and no store approval.
- Canvas or WebGL rendering with a fixed-timestep game loop, tested on low-end phones.
- Score, combo and leaderboard systems backed by Postgres with row-level security.
- Audio pipeline with beat-aligned timing, and sprite or texture atlases delivered as WebP and PNG.
- The full source repository — TypeScript, Vite — assigned to you, plus the asset sources.
- An optional itch.io-ready build package.
Turnaround
A playable build in 14 days. One-developer projects complete in 30 days; team projects in 45 days. Milestones are dated in the order.
Revisions
2 revision rounds per milestone are included, against the playable build at that milestone. New mechanics are a change order at $115/hour, not a revision.
The dated-delivery guarantee
We agree your date before we start; if we miss it, you don't pay for the late deliverable. The date is written into your order before any work begins, and it is the date we plan the schedule backwards from.
Proof of work: a game we shipped on this domain
Reactive Rhythm is a browser rhythm game we designed, built and launched ourselves. It runs on tracks from AI Radio, keeps a live leaderboard, and routes a share of Sparks back to the featured artist. Read how it works, or play it now — that is the whole portfolio argument, and it takes ten seconds to check.
Questions we get asked
- Can I see something you built?
- Yes. Reactive Rhythm is live on this domain: a browser rhythm game with a leaderboard, running on real tracks. No demo reel, no case study — the actual thing, playable.
- What kinds of games do you build?
- Browser games: rhythm, arcade, puzzle, idle, and promotional mini-games for a launch. We do not build console titles or large 3D open-world projects.
- Do we own the game and the source?
- Yes. The repository and the asset sources are assigned to you on delivery. No revenue share and no hosting lock-in.
- Can it be a marketing game for a product launch?
- That is the most common request. A short playable tied to your launch page, shipped on the same date as the page and the film.
- Does it work on phones?
- Yes. Touch input and mobile performance are part of the build, tested on low-end devices rather than assumed.
