The game looks lovely and feels good to play. I liked the main character's design and the environment looks great too.
But I didn't really enjoy the puzzles. It seems that most rooms aren't really a part of the puzzle but exist just to obfuscate the solution. I would prefer if the puzzle mechanics very clear (get from point A to point B) and all rooms actually played some role in the final solution.
Maybe, to make the game even crazier, the game could be set inside of a giant 3D Rubik's Cube? 😁
Great job! I think your team is very talented, good luck with your future projects!
