Very interesting game, I agree with Sam it is extremely unique and well executed.

Likes: Very cool art style, very cool concept, well executed, as good as it needs to be,  I think the controls are perfect for how the game conveys its messages and fits the theme well. Music was a very nice touch

Personal dislikes:
I found it very very challenging in the 2nd section with rocks semi? randomly popping in from the bottom and top of the screen. It is very hard to predict or recognize a pattern in their spawn timing, and it didn't feel "fair" in some sections.

With a big monitor the screen for the game was very very small, not a major issue just harder to see the small rocks

The moving parts in section 3 felt a lot better, it was easier to predict when and where certain rocks were coming as it was simulating an orbit around the major "planets".  Perhaps having lines showing orbits could help with predictability

Some points in time the auto scrolling felt too fast or too slow, it was never horrible to work with but didn't feel the best especially if you have to wait through challenging areas.

It was definitely worth the effort to play through! Good Job!

Love this take on the theme romance! Very unique game and I love the storytelling of lune and soleil. Very frustrating and challenging game but it was fun. Only feedback I have is that the pause button is hard to use since it requires the mouse, would have liked to use escape instead. Also the transitions between levels feel too long, I wish it was faster or if you could choose when to go to the next level. 

Overall great work!
