Thanks :) Glad you liked it.
For rotation, Z or Q will rotate in anti-clockwise direction and E or C will rotate in clockwise direction. Sometimes, the directions will mess your brain if you start from top or bottom( It did mess with my brain too :p).
For two hand play, you can control the pivot with arrow keys on right hand and rotation with z/c left hand.
Overall, will rethink the button mapping in the future! Thanks for the feedback
