I like the simple and clean visual style, the tranquil music is great and helps you focus on solving the puzzles, and the concept is basic but still challenging. I just wish that the game still kept the colors at the bottom because I feel it’s easier to switch between the colors this way — perhaps it should be considered as an option. Another thing I found weird was the loading times between stages — it seems a bit long for what it is, and I hope that the developer optimizes these loading times in the future. And finally, I would like to see are more levels added eventually, as it would increase the longevity of the game. Other than that, I think Polycolor is a pretty solid release so far.
