These questions from beginners are to be expected because of how different Cogmind's world is from other roguelikes (and games in general), but I don't feel that it's a standard roguelike tutorial's place to teach
tactics and strategy, which is where these players are primarily failing. (As you mention, what they need are "tips and strategy guides.") Modern games do tend to hold players' hands and provide that kind of assistance, but I wanted Cogmind to be more about closely observing the world to figure out how to survive.
That said, it's easy to be overwhelmed because there is a lot going on, on multiple levels, so it does seems to take a more dedicated, relatively skilled player to learn quickly enough how to survive the early game,
or someone who just goes and reads a list of tips from an outside source, like our beginner's guides here
On my list of features under consideration is an in-game tips/strategy help system, but I'm reluctant to add it because it ruins the atmosphere I want to create,
and more or less the same results can be achieved by reading an outside guide. (Note the in-game tutorial is for
mechanic purposes only.)
I could also add a basic survive guide as an early section of the manual itself, and suggest players who are having trouble read that (it could even include some spoilers and a spoiler warning). The tutorial messages could mention it as well, after a number of early deaths. This is the first thing I'd try, as it's the least intrusive.
