This is something really simple, but very helpful. If you want to make the repetitive testing of your game go faster, you can speed up the entire game with the script call:
Graphics.frame_rate=160
Edit correction: The max frame rate the game will run at is 120, even if you put higher numbers like 160.
Frame rate at normal speed should be 40, so that's supposed to be 3 times faster (it likely won't achieve that exactly due to pc constraints, but will still make things quite a lot faster).
So to make it even more convenient, you could make a common event like this:

This will make it so that when Switch 1 is on, you can turn on the speedy mode by pressing 'W', and switch it off by pressing 'Q' for the parts that you need to tread carefully. Or you can use whichever other input keys you prefer, of course.
Hope that helps. c:
This is highly useful.
I always wondered if this were possible.
