Well, it's a bit late for that option now. Downloading that 100% save popped literally like 300+ achievements at once (which honestly should have popped already but whatever).

(The problem is that it's pretty much a true 100% completion save, which means that I now have nothing really to do or unlock. The 100% save I had before was 100% before a ton of updates were made to the game in the past year.)

No. Somehow the cloud save and my local save got confused, and I think the cloud save overwrote everything with a blank save file.

God, it's been so long since I last played Isaac I have forgotten what all the items do.

I downloaded a 100% save file from some website but it's not quite the same as my old save. I suppose it'll have to do.

The best lack all conviction.

I know how this guy feels, kinda. I hate onions.
