This game is very barebones, but here's what I think:
Roaming around without aim is not the most engaging experience. I would make the maze smaller and the threat more obvious and avoidable, play with claustrophobia.
Give more agency to the player. I don't know where the objectives are, but if I could control the torch consumption, I may be able to play around the challenge. Currently, as soon as the torch goes out, I can't do much about it unless I remember where the pickup was, which I don't because it's a maze.
Making mazes feel fun is very hard.
