Really nice stuff! As other comments say, I do think the sensitivity is a bit too high, and a crosshair would be helpful. Other than that, the music does get quite repetitive after a while, and I do wish there was an ending (unless there is one and I couldn't get it). Regardless, the concept is really creative and is an awesome interpretation of the theme! May I suggest making it so that each of the levels have a new mechanic, maybe even adding decimals and fractions to spice things up?
Wonderful job, excited to see more!

Thanks for the review and suggestions! I was originally only going to have one level and make it last forever but did end up creating a few different ones but the score to achieve to actually get to them isn't balanced very well... (and the last level just gives you "survive" as a goal like Halo Reach). And yep the way different elements are introduced is quite poor too, you start with 4 guns and there's no introduction to what they actually do differently...
