Fantastic, I love how the powerup coins gradually open up the building mechanic to different uses. Brilliant design and great levels!

Awesome job!  I thought the music fit well, the build ability was a cool feature.  Transitions between levels took a little too long.  Maybe a transition affect at the beginning of the level to help the player see the goal for those levels with the "leaps of faith."  Adds a little memory feature to the game.
