The graphics are certainly high quality, and everything looks and handles professional. But I guess it's got to, after 2+ years of work ;). I'm not that familiar with match 3 games, but the idea looks pretty interesting.
Anyway, I noticed the original Construct 2 loader (just the loading bar) was still initially on screen. Then it disappeared and the fancy rotating loader showed up. Me being a bit of a perfectionist there.
Loading time is still a bit long. I don't think it is my PC or internet speed. I guess the loading time will reduce once the game is installed on a device?
As for gameplay, the planets don't seem to slide smoothly. Every planet 'connects' for a moment and then you need to slide even further.
Perhaps you could make them slide smoothly (without connecting), and once the user ends touch, then automatically align with the closest planet. I just thought it was annoying to have to slide all the way especially when the correct planet is on the other side of the ring.
I think smooth sliding could be a real improvement for gameplay speed. Not sure if it can be integrated, but I'm pretty sure you can figure it out. It will also reduce multiple touches for dragging the rings, making it a bit less 'clunky'.
Out of curiosity, will you charge a fixed amount for the game or will it be free, with ingame purchases for example?
Anyway, I've seen you helping a lot of people on the forum, so I wish you extra luck with its launch.
