An interesting concept, it's taken for granted that you have an extra lives, restart from the start of the level or even just reload the game. I like the idea of challenging this with a game that is limited to a single play-through.
Thanks for the feedback.

@Phonz My next step is to add in more enemies with better AI, different weapon pickups and an expanded area.
