More players makes the game harder not easier

[Recall]

My group hasn't played since the first version of the demo and I have quickly looked through the patches and played an extra hour or so on my own, so if this has changed in any of the resent updates feel free to let me know.

My group that played the Demo only put maybe 1-2 hrs into it and I think we beat it on our 1st try, the Demo doesn't have any real threats in the game, and I know they made managing to elevator harder in some of the updates, but I'm not here to talk about how easy or hard the game is. I want to talk about how much easier or harder the game FEELS to play with more people.

Why does playing with more people make playing the game harder rather then easier. From the small amount of time that my group played it felt like playing with more people made every interaction take a lot longer then it should. With 3 people let alone 4 why does opening a bear-trap require everyone to get 1 person out of a trap. Same with doors, if you don't have everyone spend the first 30-60 seconds opening doors at the start it take more time then it should, and doesn't really allow for people to go on there own or in groups of 2. This kind of forces everyone to go in 1 big group to doing things because if you go in 2 groups of 2 freeing someone from a trap take a really long time with 4 players. Is the increase in interaction time %100 or is it lower / higher. Or at the very least if you play with 4 people a bear-trap should have a 2 person minimum increase speed cap on it.

For example. If you play on your own it takes 10 seconds to open a trap without a tool, with 2 people it takes 20 seconds on your own, if the other player helps you it take 10 seconds again. If you play with 4 people it should still take 20 seconds to open on your own but still allow more then 2 people to help open it, so if 4 people help open a trap if take 2.5 (basically ever player just cuts interactions by half but the max time to open it is always 20 seconds)

I feel like a %50 increase is fine per person, this means with just 2 people you can still go on your own, but still be punished for not paying attention to where your heading. With 4 people you can still go out on your own but now everything takes twice as long to do.

Again, I'm not saying the game should be harder or easier to play, what I'm saying is it shouldn't FEEL like I'm being punished for have more people play with me. This game looks like it could be fun and with threat / enemies aside just feels like I'm wasting time playing with more people.

I hope for the best with your game and hope to see and playing it in to future.
