I really like the whole idea of gameplay. Managing your resources is quite a challenge and the flashlight gives just the right amount of claustrophobia. The animal sounds are a nice indication of their proximity.
Controls could be improved, when playing on full screen, the in-game pointer is not in sync with the actual mouse position. Also, I couldn't figure out how to drop some fur to make room for meat before I starved.
Overall, a fun experience and promising idea, would love to see a more polished version later. Please let me know if you plan to release a "full" version. :)
