I'm not sure I understand your question, but I'm using windows 10 with unityplayer.dll.
That answers it! You're on PC.
Can you try the download on more time? The version I originally released for PC had a bug, but I updated it yesterday afternoon. If that still doesn't work, can you send me a screenshot of what the folder looks like when you open it / what happens when you try to open the game?
Thanks and sorry for the trouble!
Okay! so I deleted and re-downloaded it to my Desktop, didn't move any of the folders or contents around, and it seems to have worked though the folder _MACOSX is separate from the rest of them and both are in my Desktop.
Ah great! Yeah, must have had the broken initial build, glad it worked! :)
the _MACOSX folder is just a weird little quirk of the fact that my dev machine is a mac, annoying but harmless. it is on my todolist to figure out how to get rid of it at some point haha
