the people who use more than 7 they know how to use construct2...
because who will do 4 layers while the free version support that? the layers that should be in all games it :
layer1 = background
layer2 = slow motion of cloud , stars,...
layer3 = faster motion of some ground , some cloud...
layer4 = effect behind main game
layer5 = the main game
layer6 = effect front of main game
layer7 = the hidden stuffs to hide the player on it while on the game like entering a house.
layer8 = a front (background i don't know what they call) but sometimes you can see it a blurry tree or rocks stuffs like that..
layer9 = HUD
layer10 = fade screen or loading between layouts
