Cartoon Mobile Game UI Design

I’m in the middle of developing a new mobile game and I’m ready to hand the entire user-interface over to an experienced UI designer who loves bright, cartoon-style visuals. The game will ship on both iOS and Android, so every layout, component and animation you create must translate cleanly to multiple screen sizes and aspect ratios.

Here’s what I need from you:
• A complete visual language for menus, HUD, pop-ups and in-game buttons that feels playful and cohesive with our existing character art.
• High-fidelity mock-ups (Figma, Adobe XD or similar) followed by export-ready asset sheets and sliced PNG/SVG files that can drop straight into Unity.
• A short motion sample or Lottie/Spine file for simple UI transitions so we can gauge animation style.

Once we’ve agreed on the overall look, I’ll expect incremental hand-offs so I can implement and test quickly on actual devices, give feedback and loop back for tweaks. Final acceptance will be based on: pixel-perfect fit on common phone resolutions, consistent colour palette, and cleanly organised source files.

If cartoon-friendly UX with a strong mobile focus is your specialty, I’d love to see a link to similar work and hear how you’d tackle the first milestone—the main menu flow.
