Thanks for looking at Pendulous! It was awesome to be featured and also to watch you play through a few levels. We enjoy hearing the tension in people's voices as they just barely make or miss a jump.
Technical stuff: The original release on WP7 was back in February and the XBLIG version followed in mid-May. Currently, there are the 16 levels you saw: a tutorial, 7 beginner, 7 advanced, and one bonus level (where you won't die). Hard mode flips the playfield (like the Reverse Cup in Mario Kart) and removes all the checkpoints.
Though we only get to work on the game in our spare time, we are putting together a level pack and a few other tweaks that should hit both versions of the game this summer. If you have a favorite level or gameplay element you'd like to see more of in upcoming levels, leave a comment at our Facebook page or hit us up on Twitter @dobettergames .
