That's strange! If you do not see the splash screen from the launcher try opening the game without the launcher by going into the data folder located next to the launcher and opening ADarkPlace.exe. Also this could be a problem with system compatibility such as not being able to play directx 11 games or having a 32bit system. Even though instead of just crashing it should have given you at least an error message or a runtime error of some sort. If you are using a 32bit system I could send you a link for that specific version. And are you using the paid version of the game or the free version? Also sending a screenshot or at least a picture of what its doing can help me fix this since I haven't had anyone have this problem before.
There is no 'ADarkPlace.exe' if i open the version that's in the data folder (the one with the face icon) i get the message:
There should be 'ADarkPlace_Data'
folder next to the executable
I unzipped the game too, so i don't understand. i added some screenshots for you to make it a bit more clear what i'm talking about. 3 of them are of the game files, and the other one is the black screen i was talking about, it just closes down after.
My computer IS a 64bit system, but maybe the 32bit version will work anyway?
i'm using the free version! thanks for replying. 
This helps a lot as I can now see the problem, it appears the game did not install correctly and is missing important files needed to run the game. Try downloading the game through my main game page here https://gamejolt.com/games/ADarkPlace/323680 and that should fix the issue you are having.
