Hello,
I am Mares Calvillio, a professional web game developer with hands-on experience building and shipping browser games, HTML5 games, JavaScript games, and Phaser 3 games for clients across multiple industries.
My work covers the full spectrum of 2D web game development — from fast-loading casual arcade games and cross-platform puzzle games, to feature-rich platformers, RPG adventures, card games, and branded mini-games. Every game I deliver runs directly in the browser, works seamlessly on desktop and mobile, and is built to a professional standard that buyers can be proud of.
FAQ
What engine do you use to build mobile games?
I build all mobile games in Unity — the world's most widely used mobile game engine. Unity allows me to build once and deploy to both Android and iOS from a single codebase, ensuring consistent performance on both platforms.
Will my game be published to the Google Play Store and Apple App Store?
Yes. Store submission is included in the Premium package. For Basic and Standard, I deliver the fully built APK (Android) and Xcode project (iOS) ready for you to upload.
What types of mobile games can you build?
I build hyper casual games, endless runners, 2D platformers, puzzle games, arcade shooters, match-3 games, tower defense, card games, idle/clicker games, and casual 3D games.
Can you reskin an existing game?
Yes. Reskinning — replacing art, audio, UI, and branding on an existing Unity game — is available at a lower cost and faster turnaround than building from scratch.
