> I think I just messed up so badly that the only way to do anything at all is to start all over in the crypt. Just arrived at this level and found I can't do anything at all except wander around until I use up all the levitation and still not arrive any place where I can do a darn thing.

I had big problems with level 3. In the end, I gave up for a couple of days, came back to it fresh, and found that trying something over and again gave me chances.

Then I restarted the level and finished without too many problems (using my checkpoints sensibly, and not filling bits of the dungeon with unmanageable numbers of blues).

I don't think there are any spoilers on the message board for this level, and I don't plan to introduce anything too blatant. However, I did have easy access to an infinite supply of what I needed. Perhaps I missed something and Sam had planned a more rational method of solving the level.

There's certainly no reason why you shouldn't be able to finish the level, but, if you've made as many mistakes as I did first time round, you may need to restart it.
