A House of Thieves
...is a level-based stealth comedy-horror game about a Thief who doesn't go shopping but instead takes his shopping list and breaks into random houses to get his things.
Hey, the game already released on Steam: https://store.steampowered.com/app/1506760/A_House_of_Thieves/
Hey, I'm glad you enjoyed it! Yes, the AI will stay alerted once he sees you (it's the same on the Steam version). You did it pretty well and still found lots of items despite the Ai running around the house. Also, you can perform several actions to distract him for a few seconds (turning on the CD player, ringing the doorbell, setting off beartraps).
