It took me forever to find the first hidden card -- the rest were more or less intuitive secret areas over a few playthroughs, whereas that first one was purely a matter of Lilac-boosting into the air whenever I wasn't sure what might be above me, until I finally found the right spot -- but I did it. Now to shave a minute or so off my time and try to get Carol. EDIT: I got the "Unlocked Carol!" screen, but the character select only lists her as a lock icon with some question marks for her name. What am I doing wrong?
Loving the game so far. No complaints about difficulty -- the first time through I wasn't sure it was even possible to die, I got hurt so infrequently. My main concern is the shield, which seems, well, pretty useless. It takes a long time to save up for it, the orb colors used don't seem to change it, and all it seems to do is add the equivalent of a single petal to your health. What am I missing here?
(The solitaire game is also incredibly simple, but, well, minigames. Better than Keen's "Paddle War.")
