We've been working on some GUI mockups the last week and here's a gif showing off the result. This isn't by far what we will go for in the end, but it's a good start!
We've also tweaked the colors some with the help of the awesome Unity assets Amplify Color and Colorful. I at least like it better this way, but we're going to keep tweaking it until it gets just right.
Don't hesitate to tell us if you like what you see, or even if you hate it. All feedback is good feedback and will help us make the perfect game in the end :D
