is it posible to replace cutscenes with a custom level in wich you can spawn text? that way can have more control over delays on text pages and more... i want to replace howto cutscene wich it seems is hard coded to show on menu even if you delete the txt file..
You just killed a kitten. Yes, of course you can do that. It's quite common in fact. You just design levels into cutscees, then use branches to activate them. There is both native and scripted branching, though obviously scripted branching gives you more control.
The only tricky part is keeping players out of the way. Common methods are turning them into a "weapon" that makes them blank. I prefer just placing them off-screen and disabling their key inputs so that pressing keys only acts as paging or exiting.
I do this too - this is how I have mutiple languages on my cutscenes.
I just suggest you to disable the save during this stages, or people will load the game during the stage.
And I disable the pause buttom too.
