I didn't know where else to say this.
Your Jam page is pretty inconsistent sometimes.
Sometimes it says web version is encouraged then it is a must and then it is not required.
And in the section additional missions, it says they will be ranked but won't "incur a deduction in judging".
But in the Judging section, it is listed and said that it is included in the overall ranking.
It's not that bad but can be a bit confusing.
