This is so good! It's clever and tight, and truly system-agnostic. A plug-and-play module you could use in a lot of games, or design an entire game around. I did a whole review here (https://twitter.com/oakenboro/status/1412652196999491584?s=19), but the short version is that if you have any interest in powers (super or otherwise), EMPOWER is well worth your time.
