I can't seem to recreate this issue, I'm able to click on everything just fine. Being only able to click on the menu means something really screwy is going on with how your exe. is running. Are you using any anti virus software that could be messing with it? Its also possible the download was somehow corrupted.
Are you running it on windows 10?
Yeah, I'm running into that same issue. I've tried running an old and new save and reinstalling but come to have the same issue I can move the mouse around and open menus but can't click on else (This is from loading an old save from 0.11 to 0.12) .
