I've got news My kid played your level and destroyed everything Much more he found that the upper floor is clickable (I tried to take the screenshot at the right moment) So he tried stuffes on a new creation like that : It appears that B is always trying to walk (funny). So let him walk : The floor is clickable, even if blocks are removed as in your design (but now he stop trying to walk) I don't know yet if it could be use in some way but that surprised me.
