Game's speed is fine as it is to me.
The problem with the claw is that it enables movement, rather than sets it in place like kerosene, or hydrogen. It doesn't force you in a direction, but allows you to turn quicker, this means that with it, you can do most things faster as it sets up movement, rather than commits. Therefore, the claws going to be taken on most ships because it allows you to be better in most situations, rather than some, like the parachute.
What it needs, is have a higher damage, at something similar to kerosene, if not higher, due to the limited time the tool is used for.
