Got through the opening obstacle with walk + jump. Placing the jump before the wall makes the idea click. The bright red grid competes with the command tiles, though — a calmer background would make the route easier to read.
Yes, the background definitely drew my attention. My note was about the trade-off: while planning the walk/jump sequence, it made the route and command tiles harder for me to pick out. If distraction is part of the challenge, that effect came through; keeping the key controls distinct could still help.
