Thank you so much for the kind words and for playing the game.
Apologies for the bug, I hadn't come across it in playtesting and was still unable to replicate it when trying to fix the problem just now. I've tried what you said (Thank you for the advice, I wouldn't have known what to try). Hopefully the issue doesn't persist but the movement does look rather janky at the moment and please let me know if anything goes wrong again.
(Someone has reached out to me about some other issues that I am also going to try and fix, but thank you for alerting me about this one.)
