Took me a second to figure out the controls, but eventually got into the swing of things. Great job with implementation. I think some tooltips or tutorial hints would have helped, but great job with  the game.

I really liked everything except the final gameplay itself. I got the first two potions right, but then it was hard to think and sort through them:). Overall, I highly rate the game!

I'm not a huge fan of memory games (because mine sucks) but I did enjoy playing this one! I'm not going to lie though i was writing things down, otherwise I don't think I would have made it to the end haha. Much like Eva said, adding in some way to help the player track various pieces and or hints would be a great addition. Nice job and thanks for sharing!
