Thanks for exhausting review, I really appreciate it! The info dump is fault of adding tutorials at the very end, literally minutes before the deadline so they're incorrectly configured in the game. Levels were also rushed at the end, which is why they're not as balances and visually pleasant as we would like them to be. We will surely address all of those things in the after-jam version.
As for the section that you got stuck - you need to move the block in the opposite direction. If you look closely at the tiles below - they appear a little different to indicate where the block can be moved.
