Background
Complex floor is a domain extension of the mathematical floor function for complex numbers. This is used in some APL languages to implement floor ⌊, ceiling ⌈, residue |, GCD ∨, and LCM ∧ on complex numbers.
For the rest of this challenge, an integer refers to a Gaussian integer, i.e. ...

Simplify ijk-string code-golf math string complex-numbers
Challenge
Given a string made of ijk, interpret it as the product of imaginary units of quaternion and simplify it into one of the eight possible values 1, -1, i, -i, j, -j, k, -k.
The evaluation rules are as follows:
$$
ii = jj = kk = -1 ...
Objective: Given a positive integer n:
If n is odd, output the list of n numbers closest to 0 in increasing order
If n is even, output a Falsey value.
Test cases:
5 -> [-2,-1,0,1,2]
4 -> false (or any Falsey value)
1 -> [0]

Interpret the stack-based programming language underload.
The stack is a stack of strings that can be concatenated together.
Each underload program is a string of some of these instructions:
~: Swap the top two elements of the stack.
:: Duplicate the top element of the stack.
