Hello. I just posted a TTRPG called 'Small Survivors'. 

https://squirewaldo.itch.io/small-survivors

What would you do if you suddenly became 2 cm tall?

This is a game where a tiny percentage of the population in an alternate universe survived a sinister conspiracy aimed at killing 99% of the people living on the planet.

Your Character will be one of the Survivors who was not killed by the conspirators, and now must find a way to live in a harsh environment and then seek revenge against the leaders who betrayed you!
