Wow! This is pretty amazing. The map is somewhat accurate and it was a joy to see how you included many of the little details in an 8bit-esque style. The subtle name changes are hilarious, the HEV suit chiptune was awesome, I just need more time to get up to the test chamber...but so far the intro tram and sector C didn't really miss a beat. Thank you for making it. <3 - Jimtendo32

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
