Definition
What is game development?
Game development is the process of designing and building an interactive game: its rules and progression, art and sound, the code that runs it, and its release on web, mobile or desktop platforms.
Games are the most engaging format there is, which is why brands, educators and founders use them. The key decisions are made before production: is the core loop fun, which platform fits the audience, and how will the game be found? We prototype early so you can play the idea before investing in full art and content. We agree the target platforms, controls and art style early, so the build stays focused and testable.
Who is it for?
Brands running campaigns
A browser game with a leaderboard or prize draw that people play from a link and share.
Educators and training teams
Serious games and simulations that teach through play and track progress.
Indie founders
Casual, puzzle or hyper-casual games for mobile, from prototype to store.
Apps adding game mechanics
Streaks, challenges, rewards and mini-games that make an existing app more engaging.

Which engine for which game?
| Engine | Best for |
|---|---|
| Phaser | Lightweight 2D browser games that load instantly from a link |
| Three.js / Babylon.js | 3D experiences in the browser, product games and interactive scenes |
| Unity | Mobile and cross-platform 2D or 3D games with mature tooling |
| Godot | Open-source 2D and 3D games without licensing fees |
Why we always start with a prototype
Fun is hard to predict on paper. A rough, playable prototype of the core loop, the action players repeat most, tells you within a short time whether the idea works. Art, levels and polish come afterwards, once the loop is worth investing in.
For branded games the prototype also tests the practicalities: how quickly the game loads on a phone over mobile data, whether the rules are understood without instructions, and whether players reach the moment where your brand or message appears.
What makes a campaign game work
- Loads in seconds from a link, without installing anything
- Rules understood within a few seconds of play
- Short sessions that invite another try
- A natural moment for your brand or message
- Easy sharing and a leaderboard or prize mechanic
- Prize draws that follow local promotion rules
Types of games we make

Live updates
Fixes, balancing and new content based on player data.
Tools, and what shapes your quote
Pricing is based on your project and agreed in your quote. These are the things that move it.
| Factor | Why it matters |
|---|---|
| 2D or 3D | 3D art, animation and optimisation usually take considerably more work than 2D. |
| Amount of content | Each level, character or item is design and art work. |
| Multiplayer | Real-time multiplayer needs servers, networking and anti-cheat considerations. |
| Platforms | Each store and device class adds testing and release work. |
| Art style | Custom illustrated or animated styles cost more than simple geometric ones. |
| Monetisation and accounts | Ads, purchases, accounts and leaderboards add backend work. |
| Area | Tools |
|---|---|
| Engines | Unity, Godot, Phaser, PixiJS, Three.js, Babylon.js |
| Art & animation | Blender, Aseprite, Spine, Adobe Illustrator |
| Backend | Firebase, PlayFab, Supabase |
| Release | App Store Connect, Google Play Console, itch.io, web hosting |
Common mistakes to avoid
What we see go wrong most often, and how a good project avoids it.
Skipping the prototype
Building full art and content before the core loop is fun is the most expensive mistake in games.
Heavy browser games
Campaign games that take long to load lose players before they start. Optimise for mobile networks.
Too much tutorial
Players learn by doing. Long instructions before play cause drop-off.
No analytics
Without data on where players quit, balancing and improvements are guesswork.
Frequently asked questions
Unity or Unreal?
Unity suits most mobile and 2D games and has broad platform support. Unreal suits high-fidelity 3D. For browser games we often use Phaser or Three.js, which load faster than engine exports.
Can you make a game for a marketing campaign?
Yes. Branded browser games are a good fit, quick to load from a link, shareable, and easy to connect to a leaderboard or prize draw.
Do you start with a prototype?
Always. A playable prototype tests whether the core loop is fun before you invest in full art and content.
Do you create the art and sound?
Yes. We produce 2D and 3D art, animation, sound effects and music, or work with assets you provide.
Can the game run inside our app or website?
Yes. Web games embed into websites and can run inside mobile apps through a web view or an engine integration.
Can you build educational games?
Yes, serious games and simulations with progress tracking, and integration with learning platforms where needed.
How are games monetised?
Through ads, in-app purchases, premium pricing or as part of a brand campaign. We recommend a model that suits the audience.
Do you build multiplayer games?
Yes, for casual multiplayer and turn-based games. Large real-time competitive games require specialised infrastructure we'll scope carefully.
Who owns the game?
You do: code, art, audio and the store listings.
What do you need from us to start?
Your goal for the game, the audience, the platform and any brand guidelines or characters. A few examples of games you like help us understand the feel you're after.
Can you add game mechanics to our app instead of a full game?
Yes. Streaks, challenges, badges and mini-games can increase engagement in fitness, education and loyalty apps without building a standalone game.
How do you make browser games load quickly?
We compress textures and audio, load assets progressively, keep the first scene small and test on mid-range phones over mobile data before launch.
Can players compete on a leaderboard?
Yes. We add accounts or nicknames, server-side score validation to limit cheating and leaderboards by day, campaign or region.
Do you localise games?
Yes. Text, UI and store listings can be translated, and layouts are built to fit longer languages.
Can you run a prize draw or giveaway through the game?
Yes, technically. Promotion rules differ by country, so the terms and eligibility should be checked with your legal adviser before launch.
