Neat little game! I didn't really understand what was happening at first, so I had to read the page to figure out that left bar was a list of combos and I wasn't supposed to eventually click things over there.
If you continue tinkering with it, I'm not sure that bottom-left card section needs to scroll. It felt a little distracting since I didn't need to interact with that during the spins. I think I'd rather just see an arrow gently lit up on the right telling me there's more to look through. That way I can visually focus on the spinning and stuff in the game and I can read through all of the text without having my attention pulled back to that scroll bar.
Neat concept though, and love the combos when I get them!
