Spelunky HD - COOP score bug [READ DESC]

Okay, this bug is practically useless in score runs, but I haven't found any mention of him anywhere online, so... why not?
Basically, this bug goes like this:
1) In coop run, you should place all N amount of players at exactly same point, where their hitboxes overlaps. I also recommend to move in such a way that your hitboxes are always overlapped by each other.
Actually, this bug doesn't even requires more than 1 player. All you have to do is change the control settings so that all N players have the same keys binded. After this you can execute this bug in your run without additional players.
2) Now, when hitboxes of players are overlapped by each other and moving at the exact same time, game starts to incorrectly calculate the number of collected points. Game calculates that all N players are collecting gold at the same time, and increases amount of collected points by N.
For example: 4 players, hitboxs overlapped, collecting gold bar. Value of gold bar (on 1-X) - 500 points. Due to overlapped hitboxes, the game calculates that 4 players have collected the gold bar at the same time and increases amount of collected points by 4 - now, instead of 500 points, with this bug you get 2000 points for 1 gold bar!
Again, this bug is not very practical and basically useless for the real score runs, but I think it can be optimized more, for example - it is possible to experiment with binds, make only some of the keys same between the players, or try to repeat this bug in actual coop run with more players than 1.
By the way, nothing stops you from changing controls in the already started run!
