This game is sick! The design and art style are incredible, and the execution is on point. The sounds and music fit perfectly and create a unique atmosphere. You definitely made the right choices with your entry this year.
Making the player immortal was a great call. It allows for more focus on the fun and action. The only thing I might change is making it a bit easier to control the Leviathan. Also, I would have loved to read more about the game and on your entries page :D
