So I scanned a bit of your poem and while the meter is mostly regular (a little too regular for my tastes, in fact, but that's just me) there are a few parts that are different and kind of dissonant. For example I got this for the first verse:
-^/--^
-^/--^/^
-^/-^/-^
-^-/-^/^-/-^
See how the last line is kind of all over the place? It's got a whole extra foot and the first three quarters of it are kind of loose, so it falls apart in the reading of it. It probably wouldn't sound so off if the meter wasn't as regular for the first part as it is, but how it is now they kind of clash. Something like 'And then to save the world' or 'And save the world or something' would fit better. With the second you have the added benefit on having the joke of the line as the punch-word, as opposed to world.
In the first line of the second verse, it's really weird for gonna to be accented at all, but it seems to fit best with it on the second syllable, so maybe think about changing that? Going to has the same stress pattern, although sounds much more stiff. Furthermore, the last line is hard to read rhythmically. That'll is hard to say as one syllable, but the line pretty much requires it, and encounter really throws off the pace of the reading. Find or get to or something similar to one of those would probably have a better flow.
With the little chorus part, I'm guessing your using means as in 'the goods necessary to create' which is a really unorthodox usage. Maybe try something like 'But for this case I've prepared.' Fewer syllables, less obscure meaning.
In the third verse, the last line is really tangled up. To keep with the meter I basically have to read 'how am I even' as only two syllables. Maybe something like 'How do I manage to even score a hit' would work better. Although I find the rhyme at the end kind of trite and forced, that might just be my inclination to find all rhymes forced. However, it does feel especially so.
The rest seems like it's better off, although I didn't really make it than far with my scansion because the subject matter doesn't really appeal to me.
