I would say like EVERYBODY in game jams made the same experience like you and underestimated the time issue atleast once xD For me it took like 4 gamejams to learn how to manage the time right. But even then bugs will always just appear at the end, never actually during the process :v
Long story short: I still like your game since it inherits a valuable lesson <3 You are now one of us!
