Thank you! Yeah, I was worried that it was a bit confusing, sorry about that.

I did really like the mechanic once I understood it. I think it's just hard with jams because you have so little time to get the player up to speed. Unlike a regular game, where they are a lot more invested from the get go. Maybe having one of the signs near the X explain it? But then you run into the other problem, players don't read. :D
