Absolutely fantastic. Had to watch the video to understand what I was doing wrong (trying to put the "crafted" bags in the science/bomb thing *after* crafting them, rather than putting the ingredients in) but once I understood it was very smooth. Can imagine it would be very fun to play with a group, and probably my favourite so far in terms of polish and theme. Feels very close to a completed game!
Fingers crossed we get to see the Yogs playing it as their own characters soon! :)
