I am so happy to hear you're doing the trench run! I have tried Project Stardust and really felt the mechanics were lacking (basically had to spam the brakes to get through it alive.) Once you get it to a point you're happy with, don't forget to put it on Sidequest. Several reviews of Project Stardust explicitly mention a desire for a Quest native trench run. I know it's a fine line you have to walk to prevent C&D, but you do deserve some kudos for what you've accomplished so far.
Thank you so much for responding! I am so excited to see what the future brings!
