I'm interested; does the program include something like a dice or something similar
Hey, great question. There isn't a built in dice mechanic currently but the engine supports custom interaction triggers, item values, and mission logic that could replicate dice-like randomization through JavaScript. It's not a out of the box feature but it's something that could be built into the engine if the concept is a useful addition.
What kind of game are you thinking of building? That would help me understand whether Orbem Studio is the right fit for your concept.
