A little fun, extremely short, very disappointing.
This game had loads of potential. Engine wasn't very original, but fun and to the point. There should be more things like the shooting of the vent, because I thought that part was really cool, albeit simple, like most of the game. Most challenging and fun part was the elevator scene. If there will ever be a sequel, I look forward to it, especially if it will be longer and a lot more interactive and fun.
Also, a lot of people already asked you this, but what is it with the terrible ending? It brings no suspense too, you just examine the body and it just goes back to the menu. What a bummer. I thought it was some bug at first, but other people are experiencing too. Terrible way to end a game, you should've at least added dialogue... Oh well, hopefully it'll be explained in the next game.
