Hey Brandan. Well done on the creation of a great menu and game scene. You have created some great assets for your prototype and they go great with your theme. Your game character is very cool and you have shown very good ProBuilder skills.
I like the consistency of your menu between scenes and the use of the panel behind the buttons. My only suggestion would be to make the button colours contrast more with the background to increase accessibility for someone who is colourblind.
Overall an excellent prototype, Brendan. I really enjoyed testing out your design.
Sam.
