I did not understand, but I did enjoy

Your explanation was buried midway through the text below the game, and the game did not in fact make itself clear. I wasn't sure if I could or could not shoot the red side walls (still not sure), or if I could or even should shoot the little things, which just looked like bullets, or what I was protecting, or why stuff exploded sometimes. I dunno, just very confusing! Still surprisingly fun.
