Thanks for the great feedback!
I added the restart chapter button for that very reason, unfortunately physics based games always have a lot of unexpected bugs, and especially for game jams it pays to have a soft reset just in case!
We have an update in works that polishes up a lot of the mechanics and game flow - which we're hoping to finish this weekend. I'm also looking at uploading some of my older jam projects (there are a few recent ones on my profile currently though - check them out! - "Jeff From Accounting" is a particular favourite of mine)
