You could have used LEVER or Prise on the first puzzle. I did put a clue in the text referring to "provide some great leverage"...

The INVENTORY is a standard command in all of these games, it con be shortened to INV or even I.

As for combining items, there is a need to 'MAKE' something in one of the puzzles. The trick is to examine everything, and look for clues in the descriptions. e.g. to chop a tree down, you might need an AXE. You might have to MAKE and AXE.

I do need to work on the help screen, the whole game is a work in progress so there is a way to go yet.
