The level is short but clever Spoiler use of the zapper. I've seen this used before to walk on horizontal fences but didn't realise it worked with horizontal bars. Given both blocks are 'half' blocks it's obvious with hindsight.This makes it 5 for me. . Thank you for sharing.
I had no idea how to do it at first, but then I quickly figured it out. It's a fun effect, and surprisingly, the many red bricks weren't too hard on the eyes...well done!
