Took me a while to decide how I wanted to play this puzzle. I ended up using one hand to click on the blocks and the other hand to press the arrow keys. Click on "colour" to cycle through color schemes. You can watch a part of the solution, then stop and try it yourself. Very nice!
Well Done! Used Google "translate" which detected Hungarian to understand some of the code. Needed to watch the Solution several times before I could do it on my own.
