Go to the patreon for updated information 5 dollars will get you every build that is currently out. https://www.patreon.com/monstergirlisland

Extract with winrar or 7zip and run the .exe also could you tell me what you bought? Because one thing tells you not to buy it.

The game is not completed yet, it has another year at least of development.

This Demo is very outdated, everything has been improved since then including graphics and even the "scene" itself.

Every girl should have 2 lewd scenes for them for final release, some may have more than 2.

Demo 2 which is a huge build of the game will show many scenes and give a very good idea of what the game will be like will be out before the end of the year publicly for free. 

There is many builds on the creators patreon right now with very good content that you can access for at least 5 dollars.

Expected Late 2018, but you could donate atleast 5 dollars to the creators patreon and get access to early builds with some really good content. https://www.patreon.com/monstergirlisland

You use Winrar 7zip or windows 10 built in unzipping system to unzip the file, then you launch the .exe file.
