[SPOILERS]

So apparently I did things in the wrong order somehow. I went down the secret staircase to the underground caverns, ran across the collapsing bridge, and eventually found the secret exit to the tunnel. I then did a bunch of stuff in the house, and now I can't get back into the tunnels because one route (the secret staircase) is blocked by the lack of a bridge and the other route (the cellar passage next to barrels) is blocked by the tunnel worm that is always waiting just inside to kill me. Do I have any options to get back on track or do I need to restart?

First, how were you able to get back to the house after crossing the collapsing bridge? I don't see how it would be possible if the worm hasn't moved and the bridge is collapsed? What is this secret tunnel you're referring to?

This should have a better title.

The easiest way to get out of this situation is to abuse some game code: just jump and drop something while in the air. This causes you to hover. Jumping again resets it, so you can continue playing as intended.

I had the same issue, I simply replaced my savefile with one I found online, search on google "alone in the dark save file"

Hope it helps.

Good evening/night folks.

U got to play from the broken bridge again.u will see when u run through the end of the tunnel where the water is the worm already awaits u.so go in direction of the water see how the worm turns into a side tunnel to cheat u and then go back and follow his way.u will see after that he will disappear and u dont ve to fight.easy as it is but no one thinks this way until one tried evrything.

There are a fair number of hints actually, including in the readables, including ones that are quite subtle but definitely there if you're paying attention. If you're only used to more recent games, there tends to be quite a generous amount (to say the least) of hand-holding in those by comparison.

Also I think at the time it came out, saving before each confrontation to e.g. retrieve your ammo in case it's ineffective would have been par for the course. And keeping a number of saves handy, of course the game only permitting six being problematic. No doubt the team would have considered making changes to the whole bridge/Cthonian (worm) area had they had more play test time.

Which puzzles did you get stuck on that you didn't think there were any clues for? Let's see if I can point at a clue for each of them, or at least some.

No problem I solved the game, as I said I'm replaying it from the childhood. But how I wrongly thought you could defeat some creatures - if I didn't read waltkhru's about what creatures are invincible I'd waste my time.

Now that when I have more critical thinking than when I played as a child, I find it way not obvious that you had to put the book right of the strange looking wall in the library, like I thought I got the wrong book and he says 'There is no room' for the strange wall, some say there is an indent there on the shelf, I have seen all library parts and the same walls can be seen elsewhere. But as soon as I learn where the 'secret place is' to put the book and with the items inside I immediately recalled which blade can kill the purple ghost.

And I had wrong memory that you could kill the sitting ghost, an why I remember that you quid kill the bath jellyfish by throwing a poker. From walkthrus I learn the poker is completely useless. And I remembered some ankh. Now I see there is no such thing just the talisman, But I remembered I had to throw a lighter or something at the tree. Then I quickly figured out what.

I read the walkthrus to see if I missed something, I think it was not mentioned how on the dark maze the door next to the start can be also opened with the hook and it is shortcut to not have to go through the entire bridges labyrinth

And if I hadn't used the bug to jump in the air, I would have had to restart the game all over as I would be stuck with the worm like the OP and was under 10 life and less all game.(I play it on Android certainly less smooth controls)

These are my remarks about how some things are not very clear to figure out.

Sorry, no notifications...

I'll just comment on a few things related to the game giving hints:

- Library: to find the right bookcase, you just search through all of them and it says "there's a mechanism to trigger". You probably found that. But I can see that the default message of "there is no room" might confuse someone in some situation. There is no indentation or gap in the books visibly but the secret door itself looks to stand out quite a lot (I just rechecked). So I suppose this puzzle is solved by searching the library thoroughly (which you would wanna do anyway to find all the books), find the secret mechanism, find a book that turns out to be fake, and infer that the book might be what triggers the mechanism in the library, which I guess is a bit of a trope as well.

- Dark maze door: That door could be a late addition to the game. Who knows? In its defense, I guess we could say it does look the same as the other stone door that the hook opens. I can see someone missing this, but it's not at all critical cause you're not getting stuck either way.

- Stuck in the tunnels post-bridge: It seems this is a very typical way people get stuck, so probably some redesign might have been worth it here.

- Defeating enemies: I suppose you could argue that the game is giving a hint about avoiding combat as much as possible by (a) being so scarce on ammunition, (b) making meleeing enemies difficult until you get the sword and (c) Emily's clue (in her intro) about the wardrobe in the loft to avoid the fight. Other than that, you're right that there's no specific clue that's present for ALL enemies that cannot be killed. There are some consistency though: the color purple (such as the bathtub monster) always means the enemy cannot be defeated using normal means, or at all; if it takes more than 10 hits to kill, you can't kill it (exception being the Deep Ones which you also can't kill with unarmed melee attacks, each attack has to deal at least 2 points of damage); it it doesn't bleed, you can't kill it (front door monster and cthonian).
