Thanks for giving my game a try and giving feedback!
Yes, I do realize there have some lighting effects and visual bugs (I believe it's just visual bugs but not actually affecting the Player's behavior). If I'm not mistaken besides the stuff you listed out, there also have some of the lights will change after the round start for a while. However, I decided to leave it when submitting to the Jam I don't want to mess up the entire system and risk not fixing it in time.
