Interesting...
The title certainly is an eye attractor, and the game itself really holds up to its name. I did however, find a few problems that kind of had me widen my eyes for a minute there. One of them was the lack of the ability to switch weapons. When I wanted to switch from the Light Machine gun to the Laser Gatling Gun (purchasing new gun of course) I found that I had to save up my points up to that point, because when I purchased from bottom to top, I found I was stuck with the laser cannon and could not change back. Not that I'd imply the laser cannon isn't a good weapon, I just bought the Machine Gun series so I didn't have to keep tapping the click button. I also didn't like how if you did complete it, the end screen looks exactly the same as the "You Died" screen, there is however, a difference where a word put on the top (not with much emphasis) saying "COMPLETE". Had I not seen this, I would've assumed that was another glitch. I suppose the fix for that is make an ending with the bonus prizes you earned/a diagram showing the "fun facts" (I.E. 300 red cans stacked up, because thats how much blood you spilled).
Overall I think this is a good game, and it could be better once those things are settled out.
A little tl;dr to the Gamers; Keep a point or two open when going for a 2 point upgrade, or even a simple one point, so that when you're about to die you can jump back up through a health upgrade (They fully heal you, if you didn't know)
