This was super fun! Loved the colours and the pace of the game, it was done really well! Everything is slow at first but when the player gets spotted, things start pacing up real fast, and while not many people might like that, I actually preferred the fast pace of the game after the owners spot the thief.
The changing items and randomised location were really fun and kept the pace up. Though I couldn't find the trophy at the very end, though I checked everywhere, but that might just be me. Making the items a little more different than the rest of the things might be good; one example is the frisbee and the candle. The frisbee looked like a plate and the candle blended into the background a lot. But I think everything was really distinct and really unique and finding each thing was challenging and really fun!
Other than that, hope the house gets better and there are more places to hide and distract the owners and maybe even opening up the yard and going to hide in there or something as well.
Was really entertaining and really fun to play! Good luck on future updates and projects!
