Create a 16:9 gaming thumbnail, aiming for 1280 × 720 pixels, featuring my [BUILD TYPE, e.g., floating castle] in [GAME NAME]. Base the structure on [ATTACHED BUILD SCREENSHOT / DESCRIPTION OF ITS SHAPE, MATERIALS, AND SCALE].

Use only two large labels: “[LEFT LABEL, e.g., DAY 1]” and “[RIGHT LABEL, e.g., DAY 30]” at the top of their respective halves. Match them to the actual video timeline. Avoid invented ranks, scores, trophies, or statistics. Leave both label areas blank if lettering is unreliable.
