sub(a, b)             * subtracts second number from first
lt?(a, b)             * checks if the first number is less then the second
eq?(a, b)             * checks if the first number is equal to the second
pair(a, b)            * adds an element a to the list b (or creates a new list from these two elements)
head(list)            * returns the first element of the list
tail(list)            * returns all elements except first one
key?(key)             * checks if key is pressed (left/right/up/down/z/x
log(smth)             * logs it's contents to the console
rect(x, y, w, h, c)   * draws a rectangle with specified color
