So, I playtested it. Usually, I would use the arrow keys to move the player. By using the mouse, I could walk around the map I’m on, but I couldn’t move from one map to the next. This is because I made it based on arrow key movement and presses to transfer a player between places. Furthermore, I had the triggering moments be on the floor, not on the NPCs or items themselves. If you directly click on a NPC with your mouse, it won’t do anything. If you click on the floor in front of them, it will trigger a dialogue moment with them. Same can be done if you stand there and press the Z key, Enter key, or spacebar. That could explain your issue there, or so I hope. 😅
