hi; I'm no expert on using construct 2; so maybe others can step in too?
If you are using the free version of construct 2? like me
I right click the object; which gives you the z order and option to send to top or bottom; however there isn't much control other than this..
I haven't found the degrees in animation; if there is any?
so i use a different software for that..
hope this as been of some help..
