Are you on Android or a Windows/linux PC (or maybe Mac)?
For PC, you need to download the (PC) version above, unzip it somewhere and double-click the TotalMaidness.exe inside the extracted folder.
For an Android device, you need to download the (Android) version above and then tap on the downloaded apk to install the game (how or where to find downloads might depend on your device).
