okay there'st wo reasons why
first, using the action 'object|spawn' instead of 'system|create' also automatically sets the angle of the spawned object to the same as the parent object, which is why they were angled to around 180 degrees.. the enemies are angled that way when they head towards the player.
so instead of spawn use
>system | create object 'pointRise' on layer 0 at (enemy.x, enemy.y)
secondly you've given each pointrise the 8direction behaviour, which means you are controlling all of them with the movement keys at the same time you are controlling your ship! so just delete that behaviour from pointrise
one more thing, you should read the manual entry about DT or Delta time...
basically any constant movement such as "every tick > move forward 3 pixels" or "move 5 pixels at angle 270" should be multiplied by DT to compensate for any frame rate jitter. (otherwise if the frame rate dips from 60 to 30, objects will move half the speed.. which is bad)
