Nicely put together, I liked playing with the physics. Good tutorial too. My only question is about the level select - are there secret levels you have to find? I couldn't select the other ones (2-1, 3-1, etc.)
dang really? there's nothing after 3-0 (all I had time for) but beating the level by getting to the teleporter should unlock the next one. In any case you can hold down p and q at the main menu to unlock all levels
