Thank you so much! We spent a ton of time making the grapple feel really good, so I'm very happy that it comes across that way. As for the player movement, we definitely could have used some more tweaking before it felt as polished as we wanted. We also agree that the difficulty ramps up very quickly, and the game could definitely benefit from checkpoints. All in all, we're very pleased with how everything came together, and we're glad it shows how much effort and time went into this project! Thank you for the kind words!
