The intro sequence has amazing quality, and the art is stunning, both in the intro sequence as well as in-game! I love the story voiceover, and the little sayings of the cat as you fly are so cute. The music is also very clean and relaxing to listen to.
The mechanics didn't quite... excuse the pun... land for me, since I'm not sure how to effectively stay within range of a lighthouse for the precise moment that I need to take an action in sync. I got a "get closer to lighthouse" message more often than not when I tried to launch a clip. I also struggled with the actual turning controls being on Q and E rather than A and D. At least for me, I think swapping these would make it much more intuitive. I found a few lighthouses but they were a bit too far apart to want to go find them all. I was hoping that the compass showed the direction and distance to the nearest unvisited lighthouse, but I think it was just the direction the plane was pointing in and its altitude, which makes sense from an airplane instrument perspective, but not as useful for a player.
All in all, still quite a nice game though. The plane's movement in general was very natural, and I like the slight floating motion too. And again the art, music, and story were all stunning. Great work!
