Found this glitch while searching for routes in 0.8.2. If you drop the suitcase at a certain angle in the checkpoint's door, you can glitch it and hit very quickly, either by letting it glitch out or grabbing and moving the mouse. Most of the time it gets thrown into space, but if we somehow find a consistent way to do it, it could be a little time save in Any%. It maybe works in older versions too, haven't tested it tho
