first objective was to analyse the reference videos and assets to identify the type of edit like cuts, pacing, fonts, sound design requested then made the required changes accordingly to build a storyline.
30 sec was very less time for the length of video provided, so first 25 sec came the introduction of the game along with objective and then a clip to hook the viewer to story / build suspense. It took me around 6-7 hours to complete it.
I mainly used premiere pro, provided assets, some of my own assets along with ai to create some images.
