This is going to be an example of a work of art that will have it's score go down by badge seekers rating it. Appreciate this for what it is! Just a really beautiful flash masterpiece.
Dude! This is such a great idea and a really cute, fun game. If I were to make one suggestion though - make it more game-y. Like, maybe have the songs in order and have a certain score on a song unlock the next two songs? Something to make it feel like you're working towards something.
Man, this is just a little too hard to be fun for me... and it's a shame because this could almost be my favorite game on here! How about giving us an easy mode with some more lives? The boss battle is brutal when you only get two mistakes/hits and you're dead. 4/5. Would be 5/5 if the difficulty didn't make it so not fun to play.
Hey, fun game! If this isn't a final version, you should save which puzzles are finished by the player and check them off in the main menu. You've done a good job with this!
Fantastic game man! Took me a really long time to figure out what was going on though. Can you add a little hover text for each card to explain what it's doing? It wasn't obvious to me how each card worked. Also, I didn't get the whole basic-stage1-stage2 progression right away. If you could speed up the game play that would be great as well - too slow right now.
