It's always difficult to get everything done in time for a game jam! I think maybe a sound effect to show you are sticking to them but can't move would help make it clearer.
I took a video of the bug I found https://bsky.app/profile/bughuntingquest.bsky.social/post/3lgeyb7tny22e and posted it to our bluesky - after the box jumps back in bounds, I am clicking on it but it isn't interactive. Eventually I was able to get it to respond but it happened each time.
