As far as a point and click adventure game goes this is close to perfection - interesting world, imaginative animation, smart puzzles and unique gaming mechanics with using the Holy Wings an Evil Wings to interact with the world.
The game is very Aesthetically pleasing, cool mixture between animation and photography. I liked how fragments classical paintings were used in this game to great functional effect, the bridge from Michelangelo's painting of God touching Adam was the best.
Only imperfections in this game are small technicalities, like lack of fullscreen, lack of animated cursor and sometimes clumsy pathfinding.
I managed to solve all puzzles trough they were challenging, except one - the one with bugs. That one required either thinking or patience I didn't have. I still find that puzzle great despite me requiring walkrough to solve it. All other puzzles were great too especially ones that required the use of Wings.
