[REQUEST] OLitD: Looking for brainstormers!

[DRedshot]

i have an idea whic i was going to use: have different solutions to puzzles, eg:
the player can either use a pot of acid to unrust a door, which leads to a new area, or he could use the acid on something else, which ultimately leads to the same place, or make it so you can sacrifice lamp oil to solve puzzles - ie unrust doors, ignite machine etc. as well as having another, more tedious solution to the puzzle.

if each locked door had multiple ways to be unlocked, it would make the player more immersed imo, if i found an empty bucket i would like to think 'i can fill this with something' or ' i could break this into pieces and use it for something'. thats just one example, but have two or more uses for each item and it will completely change the gameplay.
