Oops, sorry for all the inconvenience, but you just uncovered a bug. I have fixed it on my part, but I also need rex_rainbow to fix his behavior for this.
EDIT: rex already fixed the behavior :o, you should redownload his behavior too
While I'm waiting for rex's response, you can try redownloading the litetween behavior, once again...
Oh, and I also made some modification to your capx, basically it's something like:
1. Changing the star's sprite background from white to transparent
2. Changing various value of the litetween on the stars
3. Setting starting value on the event sheet before starting the tween
PS: To try running the modified capx, you have to wait till rex changed his Tween2Effects, or it won't run as intended.
Rex, turns out I'm saving the value in the sprite's instance, so multiple litetween will use the same value. I should've stored the value in the behavior instead just like the old tween :(.
Could you please change the Tween2Effect (at around line 69)
var value = (this.tween_behavior_type == TYPE_LITETWEEN)? this.tween_behavior_inst.inst.value : this.tween_behavior_inst.value;
var value = this.tween_behavior_inst.value;
