This game has such a mysterious atmosphere and I love the gritty visuals including the heart ui. The minimap was extremely helpful and made it very easy to navigate the lab. It may be a bit too helpful, though. I found myself staring at the phone while walking around, which is a shame because the lab looks great and genuinely unnerving.
The lab feels large relative to the number of enemies, but there is a ton of potential here if you plan to add more encounters and interactive things. Nice work on the game!
