Pixel Express demo is available. Demo contains 1st chapter with 11 levels. Please enjoy.
As for the future of the game, and release date. Right now it's unclear, and we will make a decision based on the demo performance (increase of wishlist size).
In the final game, we are planning 4 chapters. Below you can see the concept of the 3rd chapter, which is set during the Industrial Revolution and introduces new mechanics.
Another big feature that we are considering is local coop (shared screen), together with the support of keyboard and gamepad. It will work in a similar way as a regular single player. The difference is that each player controls his own set of junctions, which I assume will result in chaotic and fun gameplay.
