Prototype
Extract the "ThesisPrototype.7z" file and then simply run the "ThesisPrototype.exe" file. There is no need for any additional installation than the Unreal Engine prerequisites. If you miss those prerequisites, then a prompt will pop up which asks you to install those.
Note: It might take a second to open and start the game due to Python initialization/loading.
