Sisyphus can you be please a little more specific? Thanks
Well i try. You can make the movements manually, without behavior, only events, something like: on key pressed, player - move at angle. Or maybe, if you need only up and down become faster you can still use behavior but add a condition like on button(that moves player up or down) pressed then set 8 direction speed to 900(or how much you need). Then add event that if that key is not pressed then set player speed to default.Or maybe you can just speed up the player if he goes up and down, just add event that if button(that moves player up or down) pressed, player move at angle(angle that you need) with 2 pixels distance lets say, this will make up and down movements a bit faster.
