FREELANCE GAME DEVELOPMENT

ONE PERSON.CONCEPT TO LAUNCH.

I build complete browser games solo — design, code, art, landing page, payments.

No team to manage. No handoff between designer, engineer and marketer. One head, one shipped product. Rhythm Sentence went from concept to live in one month.

CASE STUDY

RHYTHM SENTENCE

SERVICES

WHAT I BUILD

Playable prototype

You have an idea. In two weeks you have something you can actually play in a browser and show to people.

Full browser game

Concept, mechanics, art, code, payments, launch. A finished product you can sell — not a demo.

Game landing page

The page that turns visitors into players. Copy, design, SEO, analytics, bilingual if you need it.

Monetization & i18n

Stripe checkout, license keys, cross-device unlock, and full EN/JA localization bolted onto your existing game.

PRICING

CLEAR NUMBERS

Fixed-price packages, so speed works in your favour, not against your budget. Hourly available if you prefer.
