Over 20 years later, as a software engineer I decided to recreate the software to finally fulfil that childhood dream!

Beyond sound alerts, some glow effect around an object might help? A tutorial at the start almost seems necessary so people get the mechanics, if you don't have that already. Just my $.02!
I think sound gives just the right amount of help to get you in the general vicinity of the next clue, without completely giving it away. Of course there could be lower difficulty levels with visual indicators as well.
I will definitely be adding a tutorial since the mechanics are so bizarre. I was also going to add an additional mechanic: it's not just about moving a specific object, but also placing an object within the vicinity of another unknown object.
Here is a tiny preview of the basic mechanics: https://youtu.be/cUU1HnT95RE
The idea is for the game to make logical sense, but make the player sound completely unhinged from reality "I need to put the toaster on top of the oven to make the lamp spin around, that way I can move the lamp across the room near the couch to unlock the next level"
