We're an indie studio (US-registered LLC) building a mobile sandbox / dress-up game in the spirit of Avatar World and Toca Boca — a colorful, kid-friendly world where players customize characters, explore locations, and act out their own stories.

The Role

2D Spine Animator for character and interactive object animation. You'll bring our characters to life: building rigs, base animation cycles, and expressive animations that players interact with every day.

Stack & Style

• Spine (Professional) — rigging, mesh deformations, skins, IK
• Chibi characters in the style of Avatar World / Toca Boca — soft, "bouncy" animation, no realism
• You'll receive production-ready assets: our 2D artist delivers layered PSDs with clear separation of body parts and clothing elements

What You'll Do

• Rig characters in Spine with skin system support (interchangeable outfits, hairstyles, accessories — no re-rigging required)
• Base cycles: idle, walk, run, emotions, object interactions
• Animations for interactive objects and props in locations
• Export and optimization for Unity (spine-unity runtime): atlases, naming conventions, bone/mesh budgets
• Close collaboration with our Unity developer and 2D artist

What Matters

• Solid experience rigging and animating characters in Spine

Ми — інді-студія (LLC, зареєстрована в США), яка створює мобільну пісочницю / гру-вдягалку в дусі Avatar World і Toca Boca — барвистий, дружній до дітей світ, де гравці налаштовують персонажів, досліджують локації та розігрують власні історії.

Роль

2D Spine-аніматор для роботи над персонажами та інтерактивними об'єктами. Ти оживлятимеш наших героїв: створюватимеш ригі, базові цикли та виразні анімації, з якими гравці взаємодіятимуть щодня.

Стек і стиль

• Spine (Professional) — ригінг, mesh-деформації, skins, IK
• Чибі-персонажі в дусі Avatar World / Toca Boca — м'яка, "гумова" анімація, без реалізму
• Ассети отримуєш готовими: наш 2D-художник віддає пошарові PSD з чітким розділенням частин тіла та одягу

Чим ти займатимешся

• Ригінг персонажів у Spine з підтримкою системи skins (змінний одяг, зачіски, аксесуари — без пере-ригінгу)
• Базові цикли: idle, ходьба, біг, емоції, взаємодія з предметами
• Анімації інтерактивних об'єктів та предметів у локаціях
• Експорт і оптимізація під Unity (spine-unity runtime): атласи, конвенції найменування, ліміти по кістках/мешах

• Тісна співпраця з Unity-розробником і 2D-художником
   

  Що важливо

• Впевнений досвід ригінгу та анімації персонажів у Spine
