Such a wild concept how, the music is perfect I can't believe this even exists.
So the control scheme, let's talk about this. It's chaos, I did eventually get used to it but even then it wasn't fun. I felt like it was easier to play while never rotating my octa.
I love the idea of rotating the octa and using the different arms, but I'm not sure if this is the way. Maybe using the scroll wheel to rotate, and clicking with your mouse (with the arm closest to the cursor being activated?). I just love the idea so much I hope you develop it further, sorry for the long comment ;)
And thank you for the great game!!
