This game feels like the main goal here is exploration, with the lantern scattered around they encourage the player to go around the environment and the map gives them feedback about the progress they made.
I like the additions of the map lighting up its a really satisfying feeling seeing your progress through the game. There is a little issue with visual clarity on the power-ups since they are lit up I thought they were other types of lamps that I didn't know about at first.
I would just change the power-ups to have a different visual, like a circle on the floor around them instead.
