I really like the core idea of having to keep a source of light going. The movement is well executed and feels responsive and crisp! However, I think it would've been better if each and every time you had to head deeper and deeper into the unknown to retrieve lightbulbs (or fuel) to keep the light going. Adding various random but unexpected SFX is also a great way of making the game scarier! The realities of a game jam though are that we have limited time to implement different thing, and what was implemented here is well done, so good job and keep it up!
