Game looks incredible! I liked the take on moving the the beat, and the combat mechanic was interesting although a bit challenging with how much damage it did.
I would have liked a small tutorial on how the combat mechanic worked, I had to do a few runs to figure it out making the walk back to the monsters every time. I also think having an audio element to sync up with the heartbeats to give the player feedback in the combat would be a nice touch. I ended up not being able to complete the game once I got to the snake enemies, the combat screen ended up reloading mid bar but I couldnt see the new beats and ended up failing.
Overall great job on implementing the mechanics and visuals, good job finishing the jam!
