This game is so conceptually unique and huge props to creating a chasing enemy! I do find the game to be a bit difficult but I am also not the best at parkour/platformers. I think playing around with the jump mechanic and allowing the player to jump just a bit higher for some objects it would be beneficial. The issue I'm running into is a lot of the jumps need large space/prep time but since the monster is right behind you they are difficult. I understand that is also part of the gameplay. If you are not interested in changing that another idea could be to remove colliders at the leg posts of some objects or extending the bars/landing areas for some wiggle room after certain jumps. Overall super awesome job your artwork is outstanding as well. :p
