Very clean platformer. Love the simple graphics and the dialog. Good use of the the theme!
Couple of small critiques : Would have been nice to see some type of visual feedback (screen shake or particles) when you die. Just that added juice. The controls felt a little floaty (but that could be me) for a precision platformer. Could have used a few more sound effects (especially for the guns) just to give an audio queue of when things are happening.
Great job though!
