All levels complete. Some of the final ones are nasty! Gets a bit repetitive, but every puzzle is well made, and the difficulty curve, if they are played in order, is spot on. Well designed game.
The final song isn't as epic as You Have to Burn the Rope, but some of the between level animations are hilarious. I especially liked BACKED, PATHETIC, and YAWN.
I'm amazed by the number of "needs a mute" and "doesn't save" comments there are here. Is it really so hard to read the four lines of instructions on the main menu???
