We kept contemplating what makes a "stealth" game be a stealth game and we settled on the idea that was more of a feeling that you of not being caught rather than simply sneaking around so to see a game that removes that core feature that makes a stealth game that was an interesting concept. I found the "here's the proof" to be funny and a nice touch.
Perhaps if the game offered a bigger mood of being in a stealth game such as: darker room, enemies carrying some sort of light source to have that "oh, no! someone is coming" feeling, and updating the sound to feel more sneaky like would greatly improve this game. I like the idea of removing the stress of being caught so long as it still feels like I need to stay hidden and I can because the surroundings allow me. ;) Keep it up!
