I didn't get it right away but it's quite a clever "cat and mouse" design, where if you (the mouse) gets too far away from the cat, you can't get the safety charm :O Had a few issues with the window showing on the right monitor and stuff on Linux but hey, that's Unity for you!

Thank you for playing! Based on what I've heard from a couple of people now I probably didn't make things quite clear enough. Maybe it'd've been better to have two ghosts, one chasing the player and one guarding the charm, to still make it so the player couldn't get the charm without risking their life, while also not losing the chase aspect, but too late for that now! Will update the game description to clarify at least, heh.
