Your first playable
two-player moment
A working co-op arcade loop — scoped, built, and handed to you ready to run. So you can stop imagining what two-player feels like and start finding out.
A loop you can actually play
When this service wraps up, you'll have a build you can open, run, and hand to two people. Not a diagram. Not a proof-of-concept skeleton. A real, playable co-op arcade loop with two-player input working and the core moment of shared play intact.
That moment when both players are in it together — that's what we're building toward. Everything else follows from it.
A working co-op core loop
The fundamental interaction cycle, built for two — not adapted from one.
Two-player input handled
Both players can connect and act — no placeholder code, no "coming later".
A playable build to test
Something you can run and share — so you get real feedback, not guesses.
Starting a co-op game is harder than it looks
There's a gap between "I want to make a co-op arcade game" and "I have something two people can actually play." That gap is where most early projects stall.
Input gets complicated fast
Handling two separate controllers, keyboard splits, or local connections introduces decisions early that feel minor but shape everything downstream.
The loop takes longer to feel right
A co-op loop has to feel balanced for two players simultaneously. Without a playable build, you're guessing — and iterations without runs can go sideways.
Momentum slips away
When you can't play what you're building, the project can drift. A prototype breaks that cycle — it gives you something real to react to.
We scope it tightly and build it properly
The Co-op Loop Prototype is deliberately focused. We're not trying to build your whole game — we're building the part that makes two-player arcade games feel worth playing in the first place.
We start with your concept, agree on exactly what the loop looks like, then build the co-op core with clean input handling for both players from the ground up. No solo-first architecture that we bolt co-op onto afterward.
The result is honest code you can read and extend — and a playable state that tells you whether the feel is right before you invest further.
You share your game idea
Tell us what you're making and what co-op means for it. Rough is fine.
We agree on the loop shape
Together we define exactly what gets built — no vague extras, no scope drift.
We build the prototype
Co-op core loop and two-player input, built clean and kept visible to you.
You receive a playable build
Ready to run, test, and react to — with notes on what was built and why.
What the process feels like
Calm, clear, and collaborative — without the anxiety of not knowing what's happening.
You're never out of the loop
You'll see progress as it develops. Questions are welcome at any point — we'd rather answer early than course-correct late.
Scope stays honest
What we agree on at the start is what gets built. We don't pile on extras and we don't quietly shrink the work either.
Handoff is clean
You get the build and notes that explain what was done, so you or your team can continue without piecing things together.
Something worth showing
When you play the prototype with someone, it should feel like a real game started well — not a tech exercise that "needs more work to make sense".
One flat price, no surprises
Flat rate — agreed before work begins
What's included
- Co-op core loop built for two players from the start
- Two-player input handling — controllers, keyboard split, or local setup
- A runnable playable build — ready to test with real players
- Code notes explaining structure and key decisions
- Scoping call to align on exactly what gets built
Who this is for
Creators at the beginning of a co-op arcade project who want something real to play and react to. Solo developers, small teams, and game jam veterans who know the concept but haven't found the right starting point yet.
What you walk away with
A playable prototype that proves the co-op feel works — or gives you clear feedback on where to adjust. Either way, you're moving forward with real information instead of assumptions.
A note on payment
We're open to discussing how payment is structured — splitting into a start and completion payment is something we can talk through. Just mention it when you reach out.
What success looks like here
Scoped duration
This service is intentionally bounded. You'll get an honest delivery estimate when we scope together — no open-ended timelines.
Two players in, immediately
The prototype passes when two people can pick it up and play it together without setup friction or input confusion.
Readable and extendable
The code is documented and structured so your team — or you — can continue from a clear baseline after handoff.
We build what we agree on
The scope we write down together is the scope we deliver. If something doesn't match what was agreed, we'll address it — without debate. We'd rather take the extra time than hand you something you didn't ask for.
Not sure if this service is the right fit for your project? Reach out and describe what you're working on. We'll tell you honestly whether it maps to this, or whether a different approach would suit you better.
Ask us anythingHow this begins
There's no complicated intake process. Just a message and a conversation.
Send us a note
Use the contact form on our homepage. Tell us what you're making — rough ideas are welcome.
We reply thoughtfully
Usually within a couple of business days. We'll ask a few questions to understand the project properly.
We scope together
We agree on what gets built, set a timeline, and confirm the flat price before anything begins.
Work begins
We build, you stay in the loop, and you receive a playable prototype on the agreed date.
Let's make your first two-player moment real
