+[13:11]        Dark_Fox        Well, it's hard for me to unspaghetti the code to see what's going on here, but it looks like you're writing directly to the video part of the memory each time you have an update
+[13:12]        sparky4 Dark_Fox:  yeah
+[13:12]        Dark_Fox        It also looks like a significant amount of your functions use global variables
+[13:12]        sparky4 i know
+[13:12]        sparky4 it's a game
+[13:12]        Dark_Fox        That's why your code is shit, though
+[13:12]        sparky4 ....
+[13:12]        Dark_Fox        You don't have a video buffer and you're using way too many global variables
+[13:12]        sparky4 if you want to then fix ww
+[13:13]        Dark_Fox        This is what I was talking about, you don't understand what you're writing
+[13:13]        sparky4 is it called global variables to pointers?
+[13:13]        sparky4 Dark_Fox: where the variables at?
+[13:13]        Dark_Fox        Global variables are stored in a different part of memory, so you have to make a far call every time you access it
+[13:14]        Dark_Fox        Which is much less efficient than a near call (like a variable that has been instantiated inside of your function)
+[13:14]        sparky4 Dark_Fox: ah~
+[13:14]        Dark_Fox        Which basically amounts to taking up extra CPU time everytime you use a global variable as opposed to a local variable
+[13:14]        sparky4 i know i know!
+[13:14]        Dark_Fox        You have the same problem with the video memory, which is partially unavoidable, but you need to be smarter about when and how you access the video memory
+[13:15]        Dark_Fox        Instead of touching it every time there's a change, you should set a timer that says, like, thirty times per second you update the video memory
+[13:15]        Dark_Fox        It could be even lower, like ten times per second you make a draw call
+[13:15]        sparky4 Dark_Fox: ah that is in there
+[13:15]        Dark_Fox        And everytime there's a change between those updates, you just store the update in a buffer instead
