I love the little guy manually spinning the propeller. Once I figured out how the controls worked, they were good enough to give me a little bit of control. Only a little bit. I think it's cool that moving the mouse in circles spins up the blades, but in practice I did not feel like I could make adjustments to my movement very well. I also felt like I could only descend by shutting the blades completely off.
I feel like, with this kind of gradual movement, I'd rather be exploring than dodging missles haha.
