Gorillas 2 was my first attempt at programming a game with Unity and C#.
It's very simple and it should be considered an experiment more than an actual game.
The main idea was to create a remake for Microsoft's Gorillas aka Gorilla.bas (1990).

Each level's skyline is created randomly. I also programmed a very basic AI to allow players to also have a 1 VS CPU gameplay experience.  All art and models come from Unity's Assets Store. The game was good enough to be published by Crazy Games on their website.
The game is not available anymore, but echoes of its existence can be found on the Internet Archive and on GameLoop*.
