which keys would feel more natural for you?

[bagels]

Two adjacent keys so the same hand can be used. Consider having introductory levels with lower acceleration rates.

Make P=Q, and Q=P (swap the keys)

[tgmatt]

This, or at least allow inverted controls. It feels very counter intuitive to me as it stands. Seems like it could be fun though if that's added.

Also consider a more typical control scheme: up arrow is equal thrust, left arrow is a counterclockwise rotation (but at a much lower rotational acceleration rate than currently), right arrow is clockwise
