What happened after you went downstairs? Did it teleport you to the next level or you stuck on the staircase?
I got to the next level, but the 2 blocks were next to walls, it probably is me too tired to think right to solve the puzzle.I'll get a PrintScreen to be sure.
The puzzle can be hard but they're all solvable. Once you figured them out, they will become easy. There's a nice ending scene waiting for you. You can do it!
I stuck here. I think that there may be a solution in-game for this, I'm commenting just to be sure.
I saw the solution, ahahahhsorry for the inconvenience.
No worries haha! Hope you have fun
