this is the method I use to play the 2014 version of slope. Currently the only categories you can use this version in is the pillar% and one point categories.

1. Download gameload from https://www.gameload.top/

   1.1) launch the installer and install gameload

2. Download the slope unity3d file from https://drive.google.com/file/d/1ipeeH82KE9XQsQXake20rW_mkPGXsJgI/view?usp=sharing

3. open the slopeWeb.unity3d file using gameload
