Now that I did some level making for me and my shadow, it appears to me that there is no way to do a block alignement that allow the player to go up!
The player will always hit the upper block by trying to jump to the next block.
I tried several system in my Move level and none is good. Each time I hit the upper block, and I success sometimes by total luck.
You can see the same problem in the level named "Volcano"
I think an easy way to fix this is to add half-blocks.
What do you think?
