Ye the boss did die mid jump, so was most likely one of those. I was using the webbuild when i played so probably som issue with that (i have had other issues with web version of other godot games this jam to). Looking forward to seeing the postmortem devlog, i really like seeing the behind the scenes stuff.

Just finished the Devlog: https://dragonforge-development.itch.io/eternal-echoes/devlog/968561/post-mortem... Wanted to get it done before my next jam starts, which is just under 11 hours.
