RMV is really designed for making old school JRPGs, but thankfully with the QPicture plugin and a few others it can be converted into a point and click game engine. Here are some pictures of the process. using the QPicture plugin. I can make a full tutorial if anyone is interested. First I make pictures of each area in Paint.net.
Set up a common event . Each picture will set off a different switch when clicked.
Then you need this event in every map, which gets called when the player switches to eye/hand/mouth etc. (That's another story for how to do that). This also calls that common event to set up the pictures for clicking.
The next page is a series of conditional branches for which picture you clicked and which icon you clicked it with. Note that each one turns off the switch after itself.
