that not all platforming games have you move at a fixed speed, and usually handle movement differently when you're in the air.
Donkey Kong style movement: Movement is fixed speed. You can't steer in the air and you have momentum, so if you're not on ground, it doesn't matter whether you're hitting arrow keys -- you keep going sideways at the same rate.
Super Mario style movement: Movement is acceleration-based. If you press an arrow key it adds/subtracts horizontal speed, and if you don't you slow down. You can steer in the air. (Should steering in the air be weaker?)
Do you really want to be able to jump when in the air? If you do, do you want to be able to do it continuously?00cherry
