Thank you so much for giving me feedback!
I actually used only regular RPG Maker content for the visuals! The labyrinth's looping was just to make it feel a bit more confusing to navigate, and I discovered it by accident.
I do need to balance the game, and also add something to tell the player to use the Glimmering Star, honestly. Originally, it was supposed to be an event that would happen when exiting the battle with Nothing, but it never seemed to work.
I'll have to make a few changes to it later!
