Wow, this is... really polished. Really the only major knock against it is that there are no sound effects. Besides that - it's an impressive puzzler with a great core set of mechanics and solid level design that slowly introduces them at a good pace. This is seriously impressive.
Are you really 16? I don't believe you :)
One suggestion - show a zoomed-out version of all available cards at the start of each level so I don't have to either scroll through all of them (or, as is more often the case, fail the level) in order to match them up with what's in the level and figure out a strategy.
