My comments
First off, this definitely needs a preloader. Newgrounds has some preloaders available for download, so you should have at least grabbed one of those... it's annoying to have a blank screen while the game loads; it makes people think it isn't even loading.
Next... I liked how you had "ARMOR" written with the blocks, and the intro things were cool too. As for the game itself, it was OK... not great though. It felt like I had deja vu... and those little green dots that kept bouncing off of me confused me. Also, the text at the top-left corner of the screen was too small and unnoticeable. It took me a while to notice that one of the numbers was how much armour I had left.
Pressing one button doesn't exactly make an exciting game... This game isn't awful or anything, but I didn't find it too fun.
