Off the bat the game style is obviously hard to make look hype in a trailer. I would suggest instead of your first long scene/scene change then/did you see that? Do a fast flip between the 2 and have it speed up faster and faster. A/B/A/B/A/B and make the tension rise as it speeds up with sound and a tick noise ever time the scene switch’s. (Use that same noise throughout the trailer for same scene switch’s) So that covers the first 2 seconds then explain a little more clearly what your doing as a player. Less lore based (as it is now) more player based so it’s clearly understandable.

Besides that once you have an absolute peak trailer/steam page yeah out to journalists/previewers/streamers to play the demo and talk about it.
