I was just wondering if there was any news about the game you were looking for? I also remember playing the game. I wish I could remember more, but I just remember various activities in the game, such as working my way through a labyrinth, picking up pieces of inventions along the way. After doing so, I was able to build a scuba-like apparatus, and when I finally escaped the labyrinth, I would get in the flying machine and fly away...
There was a game with the flying machine as well, and you had to navigate your way across a terrain full of obstacles without crashing...I just wish I could figure out what the name of the game was and/or where to find it! 
I played the exact same games . . . The labyrith was made up of 2 buildings, circular right? and u had to get to the other building via the scuba or water-walking invention (or maybe it was a bridge . . . eh). There was also the painting of The Last Supper there and there were a lot of side rooms connecting to the labyrinth. Inventions included the flying machine with bat-like wings, a flying object that rotated to glide/fly around, the water-walking/scuba invention, and a circular wooden invention that worked as a 360° cannon or something. There was also a pre-machine gun, that rotated forward as it used up ammo and seemed like a . . . wagon-gun?
btw, hello from 2016! XD
