The point system is bugged, and it doesn't reset as it should, easily softlocking the game as you can't complete it because upon reloading the games doesn't return your points back. Also, you can't complete it if you start a new game with only 20pts because those were the points remaining after beating the game.
Needless to say the -80pts door is pretty much a tease, as in no way you can get to that point with at least 90 points left without cheating. If you could recover points, like by saving the guy on the table, maybe, but you don't.
Half your games in the collection 5 countain frustrating game breaking bugs, please, fix them.
