Ha, yeah, I definitely didn't mean to imply the porting would be trivial. Major side note, but just out of curiosity, have you played Zaga-33 or 868-Hack by Michael Brough? They're both currently iOS exclusives but the latter (which I REALLY recommend checking out, it's a little more fleshed out than Zaga) is coming to PC later this year. They both fill a similar puzzle-roguelike niche as Desktop Dungeons but have even shorter average play sessions and a set of very simple, streamlined, elegant mechanics. The latter has some cool metagame progression/unlock stuff as well. I definitely recommend it heartily if you want to see something that manages to fit the same overall genre of DD while also bringing its own weird innovations to the table!
edit: Ah, Zaga-33 actually has a free PC and Mac version
