Absolutely fantastic work to all four of you, the end result really shows the effort you put into your game. I thought it was super fun to play, and the design was very engaging. I thought the aesthetic/visual theme was very clever, the way the rats bunch up when chasing the player felt surprisingly realistic (if you have ever been chased by or seen, a swarm of rats). The audio was nice and simple, but created a good vibe for the game too. I think one thing that would have really contributed to the game would have been sounds for the crossbow (shoot & reload), but totally understand that the time constraints of a game jam means you have to cut some things here and there to ensure it's scope is appropriate to the available production time.
I couldn't really figure out how the first theme - 'possession' was incorporated into the games design however.
For your first game jam, you all did very well and you should be very proud of the end result. Kudos to you guys!
