Love the concept of the game. Unfortunately, I couldn’t find someone to play the game with me so I have to finished the game alone. I love the character design and overall art style, especially the little faces on the clouds. The overall gameplay feels smooth and well-designed. The idea of using the light beam from the sun and moon spirits to solve puzzles is extremely clever and very well executed. For the music, I feel this piece perfectly captures the game's theme. It's a shame it doesn't loop in game.
As for potential improvement, I would love to see that the players can also have some active skills as Eclipse, just like the sum beam and moon crystal. Also, the overall difficulty curve of the game feels a bit odd to me. The final level ends up being easier than some of the earlier ones. But of course, this might be because I played it solo.
Overall, it’s a visually charming and smooth-feeling game and congratulations on finish the game with so many levels in such a short period of time.
