While there is some decent art in the game (especially the first cutscenes), it is quite inconsistent with coloring and shading. The cutscenes also end quite abruptly, making the contrast even more apparant. It also took me a while before I saw the K during the cutscenes (just add "next" to it to make it more visible). I did like how the cutscene where you get caught visualizes the health system.
I also had the same problem as Rex9999 with the first guard constantly bugging & catching you, which almost made me give up the game before I could even try. The game is filled with other bugs which, while they do not break the game, make it hard to stay immersed. For instance how moving into a wall teleports you & the camera back. I propose using something like: "if(collisionTrue(x + horizontalSpeed), y) while( ! collisionTrue(x, y)) x += sign(horizontalSpeed)"
