Very fun!
I will say that despite many close encounters with the monster it never actually killed me aside from when I intentionally let it do so, perhaps try increasing it's lethal capability through either a speed increase or more attack range. It also has some issues with its pathfinding, I'd often see it stuck on tables and walls, but that's always a nightmare to program especially in short jams like this one. Also I recommend having the key spawn in a random location along with the player as my second playthrough was much easier knowing where the key was.
That being said I absolutely loved the sound design and visuals. The area was fun to explore and the mechanic was extremely fun to use. I think if you all continued work on this past the jam you could have a wonderful product, great work to all of you!
