First off -- this game made me finally look up the titular video, and it's so much worse than I expected. Thank you for bringing it to my attention, hahaha. So, the game:
Favourite details: I like the extra steps you took to establish a few things, my favourite of which being that diversity of body type and gender are welcome on the team. I also like that you explained the GM's role! You would be surprised how many folks leave it to the reader to puzzle out. The Play section is also a great overview of how to do narrative roleplay! I feel like the tips out outlined could apply to (and enhance) a lot of games, and you did it with very little space.
Maybe next time: For me, it feels a little counter-intuitive that success is rolling under the stat, but a critical success is the highest possible roll! I imagine this wouldn't be a problem for a lot of folks, but I can see myself getting my wires crossed in-play.
Thank you for sharing your work!
