A downloadable tool for Windows and Linux

Puzzle Key is a tool to help you visualise your adventure game puzzles and make puzzle dependency charts.

Create nodes for each step of your puzzles. Colour code them to help see puzzle-type distribution and flow.


Right click to add a stand-alone node and enter some text for that step of the puzzle.

Then you can drag out in either direction to create adjoining nodes. Change their colour from the right-click menu.

Hey, thank you so much for this! It's even more comfy than yEd; but can I ask you, is it possible in a future version to add nodes connection to the bottom of each node? Ron Gilbert & lots of other indie devs mention how incredibly different is to design the puzzle charts vertically instead of horizontally, and since the "connection points" of each node are only on the left/right side, it really gets uncomfortable to design the chart vertically this way (so I wanted to ask this in case adding a new connection point is something relatively "easy" thing to do). Thanks anyway, loving this!

I’d love to have vertical connections too - I agree that designing the puzzle graph horizontally doesn’t feel quite right. Unfortunately, the GraphEdit stuff in Godot only works horizontally so it would be a lot more complicated to build everything custom.

looks good, the only bad thing i found is that i pressed CTL+N instead of ALT + n (windows) and it deleted the whole process i did :'(

Oh wow, yeah that’s a bug. It looks like it’s not doing the proper check for changes when the shortcuts are used. I’ll fix that up.

Version 1.0.3 has added the unsaved changes check where it should be.

Hi,  this looks great. I'd  love to take it for a spin. It's exactly what i'm needing.

Can you please include a linux build?

Thank you

I’ve added a linux build but I don’t actually have linux installed so I’m not able to test it properly. Let me know if it doesn’t work.

I am so sorry to only reply now.  Yes, the linux build works perfectly. Thank you for supporting the linux community :-)

The window keeps spawning quite a bit off my screen, I think its because of my resolution scaling. If its cool with you, please add "OS.center_window()" to the code for when it starts up?

I’ve made that change - version 1.0.1 for both Windows and macOS are now available.

Ah, thanks good sir!
