Looking for some help. I'm stuck at level 20 in 7x11 with walls grids. I'm left with an empty space, in the top left corner. Bug? A very twisty solution?Thanks a lot for your answer.
This is how it starts to get that top left corner, let me know if you need any more help with this one
Thanks. It will be ok for finishing the level starting with that hint.
Once again, thanks !
Edit: I was useful! Finished this level which made my brain melt a little :)
