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.
I understand there are standard commands, I just don't know what it is. I tried googling but came up empty handed.
Thank you for telling me these keywords, I will try again.
I'm always happy to get feedback, ultimately it makes the game more playable.
