The idea is hilarious, top-tier integration of the theme.
The gameplay is slightly lacking; there isn't much in the way of any sort of meaningful decision making and sort of just boils down to walking around absorbing all the hits like a sponge.
It is worth noting that in level 10, I ended up being rather confused on where to go, a likely result of the artstyle; which is good for what it is, though began to feel slightly bland by the end.
I must admit, overall I actually did think the art worked well; the contrast of the enemies and objectives made everything quite clear.
Overall, really good job on this; I like it a lot.
