I like* your pitch: Thought out thread title, all the relevant information is in the post, pretty pictures, the link was placed at the end (rather than at the top or the middle…). The only thing that could maybe improve it would be an animated screenshot rather than the two static ones to show off one of the mechanics - if that is a possibility.
.* Actually I’m ecstatic about your pitch, but I just read a bundle of release announcements that I thought had way more potential for improvement - so I’m trying to moderate myself a little.
