hi! this is pretty late- anyways, you don't need to do all that if you are on a pc, or are a windows user!
before reading bellow... MAKE SURE YOU DOWNLOADED FOR YOUR SPECIFIC DEVICE, MAC OR WINDOWS!!!!
now, let keep going!
you just:
1. open files and go to downloads
2.find the file and open it, in this case "ddlc" or "ddlc 1.1" or something like that-
3. when you are in, look for the one with the game icon
warning tho: dont go mess around with the game's files, or it can cause the game to run not so smoothly:)
another choice is to do it like this!
1. do 1 from before, but read ahead carefully!
2. ok so, you go to the "ddlc" file, click and open. look for the internet explorer icon (its blue!)
3.after that double click it! this will open the file and take you to an mini downloads page
4.now that you did that, click open, or save... i did both- sorry if that's confusing, just a precaution!
5. now open files again, go to the one called "ddlc-win" or something among those lines
6. and look for the game icon! (hint- its pink and baby blue!)
7.And double click to open it! it should open like a regular game does.
-ask questions if confused, even though i'm not so good at this myself ^^
Happy playing!
