Overview
Tracey, you have made an interface that largely follows the rules of UX if I were to nit-pick I would say that the spacing between each button on the student page is not the same and the animations provide a distraction as my eyes are drawn away from the buttons to look at the animations.
Home page
Buttons
Interactivity
The sound effects and animations both worked well to gather to make a good user experience this was because of added interactivity and enabled an audio channel for the game.
Colour
I found that the colour of the background went well with the background as a dark colour (grey).
Location
The buttons were at the centre of the page, with the combination of the buttons and title provide a good amount of whitespace within the page.
Title
I felt that the title had a colour that had contrasted with the dark background which “popped” out of the screen because of the background the purple title was easy to see for users with poor eye sight.
Background
Theme
The background of the game was a space-related image which goes well with the theme
My project page
Buttons
Interactivity
The buttons all made an interactive sound once clicked which this improved the usability of the buttons. Each button changed colour (lighter grey) once hovered hover, this colour would work for the visually impaired and
Colour
The colour was grey which clashes with the murky blue as the background as the colours we are supposed to do have contrast which positively affects user interest in the product.
Location
The location of the buttons was at the bottom of the page, and the structure of all the buttons was not continuous as the buttons were in three groups, the lack of continuity could negatively affect user experience. The middle group of buttons is also at a different height compared to the button groups at the left and right of the screen.
Overall I do not have many negative things to say because it is a good design. Great Job!
