I think the Jets are dull, there should be more movements to it than thrusting you upwards.
I've played Soldat quite a while now, and I really think improving the Jets would amuse.

The movements could be as simple as; if you tap (Down Left x2) + tapping Jet, you'd fly downwards in that direction - Instead of just flying upwards (Which really is a pain in the ass).
