Just installed it and had a play.
I really like the cube effect. It's super smooth. Only thing that a bit strange is that the cube is made up of a grey tint cube and not the wallpaper.
It would be really cool if you could 'wrap' the wallpaper around every face of the cube so you see a different screen each time you flip. Or have the option to choose a wallpaper for every face of the cube.
Be good to have a Master wallpaper which appears behind everything and then as above for the cube etc..
It has a little trouble skipping transition midway through, so if you flip before the screen has finished it's transition, the animation to the next screen it jerky.
When going from Helicopter view to the selected screen, you get this elastic bounce of the grey tint, I don;t think that need to be there at all tbh, makes it look like it's doing something it shouldn't be.
When I selected Fly in/out for the app draw it threw a wobbly and went to black screen. with that setting set it seem to do all sorts of wired things.
Also when I selected fad in/out it kept taking me back to the app draw, stuck in a loop.
Hope feedback helps:

Nice to see a home screen with more animations, makes the phone look special, keep up the good work.
