I want to have an effect for my games menu screen where when you press start a door opens and the screen zooms into the open door, but when I use increase size it caps at 125. Is there a way I can bypass this or maybe another method?

The max size for a sprite depends on the current costume - a small costume will take a larger size setting than a large costume. So the workaround is to select a small costume, set the size and then select the larger costume.
