Fungus is a tool for making 2D and 3D games, especially visual novels, roleplaying games, and hidden object games. It’s designed to help you make games without coding by using a visual scripting system (which is like making a flow chart of things that you want to happen in the game).

Unity can be intimidating at first but Fungus can help make it more accessible. There are also plenty of tutorials for Fungus and good support forums if you get stuck.
For more complex projects you can also start creating some scripts in Lua with the tool.
