Enemies spawning in after you get caught would be a cool addition. The only problem I see with how it currently works is that some levels (atleast 1) were imposible to clear without getting caught which weirded me out a bid since I wanted to sneak through perfectly. This also forces the player to get caught instead of making it an alternative option / decision while clearing the level. The game is promising in my oppinion, I think an extra day would have made this game a lot better, overall a good job to you and your team.
