Looks and works great, your controls have a great look and feel to them and are very well done, the shark looks amazing and the sand is done well.
Maybe add some things to the background like a shell or some seaweed, the reset all button resets the shark to a different position than default.
The menu scene looks amazing and I love the way that it ties in our theme, the button works fine, maybe add a on hover effect.

I like the background of your scene, the menu looks good and it shows where I can go with the highlighted selectable option, the buttons don't work for me, I am using Opera GX so that may be the issue, the character looks good but does not feel very 3d, I can tell that it is however it could be more pronounced, maybe through a different placement or a rotation to show depth.
The trees look quite nice and the mountains in the background fit the groups theme well.
I like your projects Horse, it looks a touch like a Camel.
Some issues I have with this running on Opera GX, is the horse is not loaded by default, The scene loads on the Horse page rather than the main menu and there is no background I can see, further a shrink button and directional versions of move and rotate could add to your work.
