Hmm well the 2D exploration is out of scope of my Tome project right now but although TECHNICALLY it's a point-and-click engine one of its main features is a scripting language for visual novel style dialogs. As I mentioned in another thread it is currently between very difficult and impossible to distribute a project like this and provide updates so I'm hesitant to hand it out in such an early state but if you have a good idea what you're going to need out of it maybe we can hammer out the features you need from it and I can provide a starting point :0
