Sometimes you simply need to go back to basics and find a simple, direct method of making sure your silly high-concept ideas actually work.
Recently we did that by making post-it-note cards that represented various structures in a puzzle (the first the player-character will likely encounter) and old-fashionedly made sure it all added up.
This was a success in two ways- firstly the basic idea did indeed work (always handy) and secondly we managed to identify a few canards we could simply cut without developing further. A minute saved is a minute… earned?
Anyway it is quite possible to get pretty far into something and realise you haven’t established or tested certain key elements that 100% NEED to function properly. As more hours rack up on the project we thought it a good time to actually do some safety-checking.
