Congratulations for the 8th place in the Ludum Dare 39, this game absolutely deserved it! Your puzzle concept as well as the art design may be minimalistic, but it has such a high replayability and it's quite addictive to try it over and over again. It has a bit of a "Mini Metro" vibe in my eyes, and oh boy, you won't believe how many hours I spent with that game. <3 That's why I wrote a short article about your game and also created a little gameplay video of it. :) Looking forward to your new game projects!
