I liked this game. The level design is fine although I think the sprites used to draw the level are a bit confusing sometimes I dont get if it is a platform or a pit, however event without a map I managed to find my way on it. The character is great and it has a consistent art style with the gun, light.
The gameloop is solid and well defined although I didnt reach to the endgame I liked playing it. Second ghost was tough for me, blatting it in the cold was too dificult. Good job!
