Yeah it looks really interesting and I'd love to play it, regardless of the jam. I actually unplugged everything I have plugged into my computer just to be sure, restarted the level, the game, and my computer, and no matter what i did I just could not take control of the dice. I also just tried it again right now and had the same issue. I also tried playing a few different games now to see if its a problem on my end, but nothing else I'm playing has a similar 'button held' issue, which makes me think its not a problem on my end. Sorry about that, not trying to be a pain at all.
Edit: also just deleted and redownloaded and had the same issue. Sorry about that
