One one of my usual ttrpg crew showed up a view weeks back. I pulled out this game as something to bound over and force ourselfs to be creative. It's a simple but fun exploration.

I was hoping om a little more direction on the roleplaying aspects. Though the way u are directed to create worlds is interesting & the end is something that the player and i still tount the other players with for not being there.

All and all a fun and inspiring game, especially worth a try if part of a bundle!
