I see that most of the commenters have already said this is shorter than a game ought to be (even for a pilot) but very good for what was presented, and a few people pointed out the similarities to Submachine. I'll say this: you've got a good engine and hopefully you'll be able to spend most of your effort concentrating on designing an immersive world and story for gamers, because IMO when it comes to point-and-click games in general and the Submachine series as a great particular example, that's a big part of what makes the best ones stand out. The other is of course making a variety of reasonably sensible puzzles that aren't exercises in pixel hunting. From this pilot it looks like you'll probably be safe in that regard; *** [spoiler] *** personally I would have preferred either having the grate change the mouse cursor (at least when the screwdriver is held) or never having any objects change the mouse cursor, but I can respect the design you went with considering how prominent the grate is and how reasonable it would be to screwdrive it.
