You can modify the type of the "splash" (loading) screen in the project's properties if you own a proper plan for C3.
Moreover with C3 runtime you can have loading screens in between layouts of your game if you want.
I do have a subscription and the choices for Loader style are: nothing, precentage text, progress bar only, progress bar & logo, Construct 3 splash.
Is there any inofrmation/guide on how to have loadingscreens between layouts?
