First of all, no gamejam game should have the right to make me audibly scream hahaha. The lighting is absolutely fantastic and making the walls pitch black is a great choice to really make a suffocating and eerie environment. Some commenters have mentioned getting lost, but I actually quite like the level design. It reminds me a lot of how cave explorers describe the caverns as this otherworldly and claustrophobic place where the walls blend into the darkness. The audio is also fantastic and really sells the atmosphere, in my opinion. Would love to see an expanded version someday.
