Create a 2D sprite-based level with animations and collision detection for Unity 3D mobile

We are embarking on an exciting project to create a 2D level with animations and collision detection for Unity 3D. Our inspiration comes from the beloved game Stardew Valley, and we aim to replicate its charming aesthetic while expanding the scale to twice the size of the original. The game will be for Android mobile devices. Please refer to the attached screenshot for reference. Key Requirements: Level Design: The level design should mirror the quaint and rustic atmosphere of Stardew Valley while accommodating the larger scale. This involves creating diverse environments such as farmland, forests, rivers, and town areas with attention to detail and coherence. 2D Artwork: High-quality 2D artwork is essential to capture the essence of Stardew Valley. The artist must excel in creating visually appealing sprites for characters, buildings, terrain, flora, and fauna, maintaining consistency with the game's art style. Animation: Animations play a crucial role in bringing the game world to life. We require smooth and fluid animations for characters, creatures, environmental elements, and interactive objects. Idle, walking, running, and interaction animations should be included. Collision Detection: Accurate collision detection is fundamental for player interaction and movement within the game world. The developer must implement collision detection for characters, objects, and terrain features to ensure seamless navigation and interaction. Unity 3D Integration: Proficiency in Unity 3D is necessary to integrate the artwork, animations, and collision detection into a cohesive gameplay experience. The developer should be familiar with Unity's 2D tools and scripting capabilities for efficient development. Optimization: Efficient optimization techniques should be employed to ensure smooth performance across various devices and platforms, considering the increased scale of the game world. Testing and Iteration: Thorough testing is crucial to identify and address any bugs, glitches, or gameplay inconsistencies. The developer should be receptive to feedback and willing to iterate on the design and mechanics based on testing results. Documentation and Delivery: Comprehensive documentation detailing the game's mechanics, controls, and development process should be provided. Delivery of well-organized project files and assets is essential for future maintenance and updates. If you are passionate about recreating the charm of Stardew Valley in a larger-scale 2D environment and possess the skills to bring this vision to life, we invite you to join us on this creative journey. Please submit your portfolio showcasing relevant experience and discuss how you plan to tackle this project's unique challenges.
