A nice reskin of a match four game, working well. I like that you went as far as having music and sound effects integrated, and the graphics look cute. It might have been nice to have more made of the 'no stopping' theme, as this felt like a standard match4 (which happen to be continuous play), rather than a game with a new 'no stopping' mechanic added - but you can only be a little picky when you're writing a game in a weekend, I realise, and this all works well together. Nice job.
It felt very difficult very quickly, to me - although that might have been what you were going for!
One possible bit of feedback if you want to continue this after the jam is that the 'next' player updates before the previous player has been shown yet, so I kept finding myself looking to the next graphic, planning where they were going, only to realise a moment later when I'd clocked what piece I was dropping that it was different.
