I tried to download it and couldn't play. It may be a problem on my part but I'm letting you know. (It says something about UnityPlayer.dll was not found)
I'm pretty sure you can still change the settings and say that it's not a browser playable game. Don't delete/re-upload your game, just change the settings to let us download the exe
If that doesn't work, send a message to the moderators of the jam and ask about changing your submission
It's still not visible. If you can't see it, then others can't either. I imagine it's because you deleted the files. You should get in contact with the moderators
