Thanks for taking the time to offer us feedback. When you get to the long blue wall away the end of the second level, you can press "x" to phase though that section to reach the bottom -- which will take you to the third stage of the tutorial level.
There are still some aspects of the game that still need more clarification, so we plan on adding a clearer tutorial for the level in future builds.
Thank you for playing our game, and we hope to continue expanding and adding more content to the game very soon.
