Nice game, same as other comments. I would also add that the game seems pretty unforgivable, it feels like if you get hit by an enemy or make a wrong jump you won't be able to beat the game. Also, it took me a while to realize that I could shoot enemies.
I really liked the graphics and the effect when parts of the levelsget lit up as they enter the characters vision range. I also really liked the intor cutscene. Great job!
