Thanks for the feedback!
Rules are not explicitly stated: as I read the blurb I do not know if it is hard to figure out
Yeah, that's what one of my local playtesters said. I haven't figured out the best solution yet (a wall of text won't help. Maybe an animated example at the beginning would have been better)
It is not clear that 1-player mode exists: the title screen says 2-4 players and nothing blinks when adding the first to say that it can be started
You're right. The 1-player mode was a last-minute addition. I should have made it more clear.
I appreciate your thoughts!
