Likes:

1. Agreed with @stanai
2. Clearly recognizable plane prototype structure
3. Inclusion of light source (moon or sun)

Dislikes

1. Agreed with @stanai
2. The light source and light in the playable area don't match. It seems the moon is on the top but the light is coming from left

Feedback on menu

Likes:

1. Has the main object on the menu scene
2. Sky theme clearly recognisable
3. Clear hover effect on buttons
4. Menu sitting in a clear "gap" on the background, very easy to direct eyes to the buttons
5. User guide includes the buttons that are used in-game.

Suggestions:

1. Buttons could be bigger for better readability
2. User guide allows buttons to be clicker but nothing happens. I would replace them with images so people know it's just a visual cue.
3. Menu button location is consistent between User Guide and About page
4. The hover effect on buttons might have some accessibility issues. Try to increase contrast.
