What we make
Small games, built with web technology, published at a URL. There are three of them at the moment — Break Works, Formula Warriors and Block Pong — and they have almost nothing in common except how you get to them.
That last part is the actual product. A link is the lowest-friction thing anyone can send anyone. It works in a group chat, on a whiteboard as a QR code, and in an email to someone who has never installed a game in their life. Everything else we do is arranged around not breaking that.
The rules we work to
- No install. If it needs a store page, a download or a runtime, it is not the kind of thing we are making.
- No account. Nothing asks who you are. That rules out some features we would enjoy building — cross-device records, global leaderboards — and we would rather lose those than hold data on people who came to play for four minutes.
- Start immediately. The gap between arriving and playing should be one press. Menus that ask you to choose things before you know what the game is are a design failure.
- One input. Every game is playable with a single pointer, which is what makes a phone and a desktop the same target rather than two ports.
- Nothing to buy. No currencies, no energy meters, no timers running while you are away. A game should be finished when we ship it, not metered.
How they are built
Everything is web technology, chosen per game rather than standardised for its own sake. Break Works is 3D, and every run of it replays exactly — which is why a shared link carries a whole collapse in a few hundred characters rather than a video. Block Pong runs a rigid-body simulation on matter.js, which is the reason a shot two degrees off does something completely different.
This site is a static page: no framework, no client-side routing, three stylesheets and one small script that slides the header in. It loads quickly because there is not very much of it.
Where things live
Each game runs on its own subdomain, and this site is the index. Splitting them that way means any one game can be rebuilt or replaced without touching the rest, and it is why the address bar changes when you press play. Two of the three sit on game5.app, from before this site existed; they are the same studio's work and they are staying up.
Talking to us
Bug reports, questions and press enquiries all go through Support, which lists what to include. Formal operator information — company address, representative, the privacy contact — is on 運営者情報, in Japanese, as the registered details.
