"Octopus" Game — Educational Fun for Kids
Mobile Apps Design
This playful and intuitive mobile game was designed for children aged 3+, focusing on logic, memory, and early cognitive development. I worked on the full UI/UX design process: from user flow to final visuals.
The interface is bright, adaptive, and designed for independent use — even by kids who can’t read yet. The game includes multiple modes, animated feedback, and a joyful underwater theme to keep young minds engaged.
Visual-first UX
… Bright, bubbly UI
Game modes like Time Attack & Timed Game
Animated feedback, fun rewards, and easy navigation

Interface Design (UI/UX)
About This Project
"Tower Masters: Strategy War" is a #mobile strategy #prototyping #game where players build and upgrade towers to defend their kingdom from waves of enemies. The goal of this project was to #design an intuitive and engaging #user interface that enhances the #gaming experience while maintaining a visually appealing and strategic feel.
Challenge
… The main challenge was to create a #UI that balances complexity and #usability. The #interface needed to provide quick access to essential #game functions while keeping the player immersed in the battle. Additionally, it was important to ensure consistency in the game’s aesthetic while optimizing performance for mobile devices.
My Role
As a #UI/UX designer, I was responsible for designing wireframes, #creating high-fidelity #mockups, and #ensuring smooth navigation. My focus was on crafting an intuitive #user flow, optimizing the #layout for different screen sizes, and developing a #design system that aligns with the game’s theme.

Mobile Apps Design
#In the development of the #mobile application PolyglotPro, I started with #researching the target audience and analyzing their needs in learning foreign languages. Based on this, I created prototypes and wireframes for a convenient and intuitive interface. I carefully thought through the user experience, ensuring ease of navigation and content accessibility. During the design process, I actively collaborated with developers to ensure seamless integration of the interface and functionality. After that, I conducted usability testing to see how users interact with the app.
During the development of the design for Mobile App PolyglotPro,
there was a workshop with a mobile app developer. The result of the collaboration was a prototype of a mobile app for the iOS platform, which is available for testing in TestFlight.

Oksana is a designer I want to work with again. She very clearly understands the user, even when it's a 3-year-old child. Her approach to structure, visual style, and game logic impressed me as a mobile game design client. Everything was done with attention to detail, responsibly, and with heart. I sincerely recommend her for projects where empathy, understandable UX, and a playful approach are important. I recommend
