UBBCode is disabled for new accounts. I moved you from the new user group to the user group, so now you can use UBBCode, and don't need captchas to post, etc. Just edit your post, optionally take out the sentence saying UBBCode isn't working and then 'change post'.
The main characters started of with specific backstories, personalities and appearances. When that was changed there wasn't enough time to add full customization of body types to character creation.
Keys only show up in the 'keys' section of the inventory, so they don't clutter up 'all'.
For that key I don't recall having to hit Alt to pick it up. Moving the camera or zooming in may have allowed you to get it, as well.
There are also teleport spells to get past the rope, or Telekinesis to get the chest.
The size of the footprints on the beach west of the harbour, and the orc, comments your characters made, the bodies on the beach and the conversation with the guard at the gate should have indicated the area might be difficult at your level.
You can separate characters, and have one explore alone, especially when you are warned there are traps. You can not control summons, but earth summons have good perception, and summoned way from the character, they can trigger traps walking back (don't think the spider will, IIRC).
