Customizable word game for building a domain-specific vocabulary

I wanted a fun way to become familiar with 75 words from the "needs vocabulary" of Nonviolent Communication (needs like "respect", "warmth", "purpose", etc.). There's a free customizable word game called Hangaroo that you can download for Windows. The kangaroo that you are trying to save is pretty snarky ("What are you, stupid or something?"), which is a perfect backdrop for the subject I am studying.

Here's a 75-word Nonviolent Communication Hangaroo file that you can load into the program.
