Yeah, Tuesday would be fine. At least participants would get two weekends' worth instead of one, so they could knock quite a few games down back then. And yes, I know in itch.io jams you don't need to rate games, but I prefer to play a whole bunch of them if time permits. ^^
Speaking of rating queues: does itch.io have system for these in the first place? Either way, to support rating games semi-evenly, I think the Jam Player I mentioned in another thread might come in handy, although it handles only Windows and web games. But also, if a game is Linux-only or Mac-only, then people who are on Windows to begin with wouldn't be able to judge these anyway. If you're interested in using Jam Player for this jam and think there are some relatively small features that could be implemented to make this jam easier, feel free to let me know. I can also gather the entries after the jam and prepare a ZIP, hopefully it won't take more than a day.
