Tomorrow I will upload a new Blob From Space update. This has a new tutorial level including the wall jump (see picture).
The first level after the wall jump will have only 1 enemy (The flyer) and it will teach you the flying mechanics.
NOTE: The flyer graphics will have some bugs. We are trying hard to fix it, but we can't keep you guys from this next update tomorrow, because we do want to show you we're working hard on this game.
Have fun,
:jos:
