Pretty good game :) The best kind of jam game for me: Simple idea, good execution and clear instructions. I have to say I wouldn't play a game with Solitaire if I didn't see that you commented on mine, so it was a big surprise to me that I actually enjoyed it. It felt a little like solving dynamic, changing logical grids which is actually quite fun for me.
For the future, as a mobile time killer that actually requires some brainpower not jus simple clicking - I would definitely play it at work :D
It could use some audio though (or maybe it just wasn't working for me? but there weren't any)
One thing that was kinda surprising for me was the "1" card. Never seen it in regular deck of cards, and I deal with cards a lot, so that grinded my gears a little, but that's just a personal thing, and I understand that it's much better for clarity for other people.
Overall: Very enjoyable experience with a potential to land on my phone if released after jam in mobile version :)
