I know it's late and I know most people won't care (because Amnon and Mark are the only one who have reported solving the level) but I *think* I've managed to fix all the remaining problems.
Aside from that 4-spike one tile to the right of the yellow button, I've added one other 4-spike into the potential "version D"... it's one tile above the pink gate.
I'm sorry, Amnon, but that extra box makes me fear all sorts of potential shenanigans, even though I have no idea what would they be. You shouldn't be able to use your box-saving solution to the bottom left corner now.
I still have less time than I would've liked (though more than before) and my primary method of testing is "finish the entire level successfully" and with a level as big and tough as this one, it does take some time. So I'm not uploading "version D"
just yet but if anybody (Amnon? Mark?) wants to try, these two spikes are all it takes to convert "C" into "D".
And then "D" will stand for "Deception".
