I am hoping this gets fixed

If the developer is reading this: I only got one stupidly high score with this (on one survival level), I've been using cheats to reduce my score to keep myself from cheating good player that actually took their time to learn the pattern

The Dev may take out all my scores from the leaderboards too, even though I didn't use this trick on all stages, I will take this L and accept having to re-play stages for legitimate high scores
(although I now notice that multiplayer scores have their own symbols..... so that could make it easier to discern)

Edit: I understimated the amount of points from diamond score multipliyer, I am sorry ;-;
I will use more in-game cheats to reduce it even further

I am currently unable to record video evidence, but the glitch is somewhat simple to follow

I was trying to cheese the game with an app called "Keyboard Splitter" that basically let's me play multiple player on one keyboard, everyone mostly synchronized, as sometimes they will de-synch for some reason, and then noticed my Diamond count was oddly high

It seems that if 2 or more players are on the same pixel location, the diamond picked up gets multiplied

I suspect the developer knew about this glitch somewhat, because when a Diamond comes from a foe defeated from the edge of the screen, it goes towards the center of it, most likely to keep players from huddling in a corner, which where you can have most players on the same pixel location

I've tried testing this with two players (mouse and keyboard, not on the same spot) to see if it was intended for more players to get more diamonds, but it doesn't seem that way

The game is also coded to accept more diamonds than 13 (the max on a regular stage) because of survival mode, where you can get well over that

I will be editing this guide as days go by to see if I can figure out more stuff, and hopefully add video proof while possible

Oh if this glitch ever gets a name, maybe try Pixeled Diamonds, since it seems to require pixel perfect accuracy
