Interesting hammer but I didn’t like the finish as B missed first time. An extra grass block would have been kinder.
@Bob Marley . Your comment makes me think i might have the wrong gameplay. Spoiler: Ending B autopilot towards the fence on rail but fell slightly sideways and wasn’t able to stay on the grass block beside the winblock and got isolated on the lower grass block. So a winblock with two grass blocks next to it would have given me the winblock first time.
Original idea, non-standard gameplay, beautiful symmetrical design, quite difficult. For me it's 5. It was difficult for me to get to the other side, with the final trick I was lucky the first time.
