I simplified the capx, I think it was a bit too early to split all into different eventsheet... always hard to read for others.
Well anyway it seems the set angle of motion is a bit bugged, I switched to set angle and that works fine (event 30 and 31)
Oh damn! A big sprite for the whole level?... crazy guy, use tiled background and some neatly splitted sprites (you could event use them for collision detection... 2 birds with one stone)
