I really like the idea of switching between modes with different abilities. It kind of reminds me of Mega Man, and having to switch to different abilities to solve problems.
I found switching modes on keyboard and mouse to be unwieldy. I think for any kind of radial menu on desktop (without a controller), being able to select with the mouse should be standard. Because of that, I had a hard time switching modes fast enough, especially given the limited time. Regardless it's a cool idea and I have to appreciate the work to add all those different modes and sounds.
