I took the initial "type" to be more of a difficulty or question-types, not about missions. Even so, clicking the bottom I get this:

> The mission of your game. Complete all your levels and achievements, and you can return to London a success. Can you go to London yet? Nope!

Which is both confusing (I am in London) and aimless ("Do everything"). Definitely needs some more attention.

I also wish I could click-and-drag the cards, or simply click to focus, keeps tripping me up.

Ok, great to know. The achievement logic is half-baked because I don't really know if people would care or not. The way I'm reading you it sounds like you, at least, would like to see it more fleshed out. Which is cool, I got a ton of ideas for it!

Why would you like to click-and-drag and focus on the cards? Where would you drag them? This is interesting, I haven't thought about this at all.

It's a view of cards, so I want to pull them left and right, I guess.

And.. well, I personally probably won't play it to be honest. Maybe if I had kids and the experience was a v1.0 instead of v0.2 I would be interested. Even then, it would be relying on my nostalgia around the Backpacker games. I'd definitely recommend getting feedback from people expressively interested in it.
