I'm not knowledgeable enough about chemistry or physics to fully enjoy this but wow this seems like a super complex game that would be really amazing for a certain type of crowd. The visual style plus the music is what really sold me on this. It's also super simple gameplay wise but I can only imagine the depth it has.
For me personally I followed what instructions said (orange arrow = put blue ball in, and blue arrow = put orange ball in) And I managed to get one of the big balls to level 5 but struggled to do much beyond that point and scored a measly 350 points. I wish there was more of an indication as to how to get the more complex elements but I guess I'm just the wrong audience. Also maybe letting you control the camera when pushing a ball could be nice. Otherwise this is a really impressive game and i love the ambience and aesthetic so much!
