Thank you!
We are aware of this bug, but unfortunately it is not a quick fix, so we couldn't fix in time for the jam. Good to know you liked the game tho. We put checkpoints frequently as the game is hard, and to slightly negate this issue. To restart to the checkpoint , just do it by pressing R .
And also we will be making a remake . With better grappling mechanics better movement and such , so if you would like to play it when it comes , just stay tuned! I hope you will check it out
