Regarding the Level 2 - "Can you pick me up?" - you have to think a bit outside the box here on how to get Bob to the goal. I hope you will try again, so you can get to the secret ending too.
I agree on the slipperyness of Bob, but it was meant to be part of the challenge since it is a bit restricted by the single-screen-layout.
Seeing you're not the only one giving me feedback on the controls I will definitely work on that in future projects :)
Thanks for your feedback
