In event 3, change the Pin action mode to "Only position" instead of "Position and Angle". This fix the problem.
This might explain why your NME didn't rotate after applying the container.
[quote:1wpdr1b1]3. If a condition picks one object in a container, every other associated object in its container is also picked.
You have an event (16) to set the angle of sprite4 to the player. Since NME is in the container of sprite 4 and also have the Pin action mode "Position and Angle" in event (3), NME will pick the angle of sprite4 everytick.
I find myself enjoying your game. Keep it up! I am looking forward to playing with upgrades and more
