Welcome to the forum. I gave your level a go but gave up very quickly as I'm not very good with tossing B even though I did get it twice. I wasn't seeing a way to the win short of a ToA which is a trick and I don't know if that is your intention? It's possible that your articulating arm may push B down but I didn't spend the time on it.
Won with zbot and with B . I presume with B is the designed win and i did like his balletic finish that happened each time i tried it. I thought that the final move is quite well disguised.
I won with zapper and i dont use B . I just smash zapper with like hammer and it fall on the win..i know i'm cheated but i'm done....hahahahaha
