I didn't bother looking at the controls in your page at first, so I was stuck at the title screen for a bit before I realized was possible, but when I figured it out I felt pretty cool! I feel like the conceit makes for a solidly fun puzzle platformer, I think just making the execution clearer would really be what sends it to the next level. I wasn't sure if there were meant to be specific pivot-point blocks that I was supposed to be pivoting off of, or if I was supposed to be pivoting off of the mouse cursor at times since sometimes I would be able to pivot off of nothing in mid-air. But, cool idea all the same!
