I have fixed most of those issues since submitting to the game jam, so I am definitely well aware of them! The browser version is a bit glitched depending on the browser type as well as some other random factors. It's why I've noted that the download version is much better--doesn't have those same issues!
I'm glad you enjoyed it and thanks for the feedback. Keep an eye out for updates--I've already fixed most of the problems from the comments!
