I also had this problem with the jump circle not working. When I jumped normally the number was not counting down. For some reason though, I was able to get it to work by jumping in a very specific spot while walking into the circle and spamming space bar at the back of the circle facing the counter. No clue how this worked but it did. Great game btw!

Thank you for sharing this, I definitely need to try and suss out what's going on here, it seems to be a pretty rare bug that's only affecting a few people.
Would you be able to share your OS and browser that you were using please?
Thank you for sticking with it and finding a way for it to work as well! Really appreciate you taking the time to play the game, hope you had fun despite the jump circle trying to sabotage you!
Scratch that - great news I've found the cause. It's a race condition caused by a mismatch between the physics process and some checks being done in the _process loop. And this race condition manifests when the framerate is under 60.
I'll be able to get a fix sorted, thank you very much for reporting this.
