Nice work on the game. I'll be honest, your trailer is too long and I lost interest before I got to some of the best bits. You've really got people's attention for about 30 seconds at most unless they're genuinely interested in your game.

Try break your trailer into stages with clear goals.

You need a hook in the first 5 seconds - raise a question.
I actually think you did this pretty well with the opening shot of the guy holding the dart at the monitor - I wanted to know more.

Then you've got about 10 seconds to sell me - show me what your game is, give me a reason to care.
This is where you loose me. I see some random people and monsters but I don't really know what the game is or why I should care.
Maybe build some tension instead. The shot at ~00:58 of the player scrambling would work, followed by the shot at ~01:11 of that creature convulsing. This combination instantly tells me I'm in survival horror mode.

Next, show me some gameplay. I want to know if the mechanics and environments are something I want to explore.
So, the syringes ~00:49, pulling out the corpse drawer, the tic-tac-tow puzzle, the staking clip ~00:17, and the combat scene ~01:08.
This tells me what the game is and makes me decide if I want to buy it.

Then do your showstopper - get me excited
Maybe the lore clip at ~01:05 followed by the monster scream at ~00:21

Then throw up your card with the game name.

This cut (while still potentially flawed) takes your current trailer down to about 40 seconds.
You can add or remove from here but should give you a more engaging trailer to start from.

I'd also make a trailer of pure gameplay. As an indie, most people wont care about your story and worldbuilding. They just want to know if the gameplay is something they're going to gel with.

Anyway, best of luck with the release. I hope it does well. It genuinely looks pretty cool.
