On a first quick glance:
The zero angle of an object is on the right. That is why in the first capx 'Rocket' is placed horizontal, facing right.
In the second capx (yours) 'BOOSTER' (wich i think is 'rocket') is facing up.
Meaning: the graphic representation = misaligned (90°) to the event system handling the angles.
Or, account for that misaligned in the calculation of the angles.
Or, rotate the the graphic content of the sprite, (in the Image and Animations editor -- https://www.scirra.com/manual/48/image- ... ons-editor ) so as a result the content is horizontal and facing right.
