The old jam version was a great proof-of-concept in my eyes, and your game absolutely has potential to become something bigger. :) The need to think in the 3D and the 2D perspective at the same time to solve the puzzles was a great approach! That's why I had to include your neat game in our compilation articles about the Ludum Dare 38 as well as the corresponding showcase video, along with two other games. <3 Keep it up, you are talented game designers!
Best wishes,
Sebastian
