Heyy, I'm so sorry about that!
It very likely COULD be a bug, there's a lot of little things I probably didn't account for and am unaware of.
I recorded a walkthrough of the game here, so if you'd like you can see what the intended solution is for that area:

Also, if there is a gamebreaking bug in a level, I do have a reset level button hidden in the options menu. But that's not super ideal LOL I'd rather just have things work. Sorry that happened to you!
Thanks so much for playing though, I really appreciate it :)
