Maasa, awesome work!
Scene design was excellent and aesthetically pleasing. Feedback from the buttons made navigation through the multiple scenes simple and accessible.Use of contrasting colour also helped make buttons easy to read and accessible.
The only UX issue I encountered was the menu and scenes buttons at the top left of your game scene seemed a little off scale for the rest of the scene, leading to a little lack of consitency, thats only the real nitpicky thing i have however.
