Good idea for the game. I think it is actually so cool to play Half-Life in style like that. I give minus for shooting.

The idea is fantastic and while the realization still has some flaws (player can't shoot diagonally) the game overall is great!

Love the simple style, very well made, and this is actually one of the few Half Life flash games that are you know, an actual game. So even though I haven't played through the whole thing, I absolutely adore it.

I want it on a ROM to play on a REAL NES

This is shit but, not becacuse of the graphics.
