I was thinking about this more in depth and using Inkscape for visualization and I think I can simplify this by weighting the cells.


Each cell weight would be the total number of possible 4-connect moves and it would be updated after each move. A weight of 0 indicates a cell that is the single point of exit for a color and is thus blocked for any other color. With this method, the correct route should end up being the "cheapest" route. Interestingly, in the example below, I ran into a case that is unsolvable.



This isn't perfect, but it seems to be a good starting point.

I don't think that the walls can be high enough. Gravity is that same at "ground level", but the mass of the high (30 km) is missing to get the right groung leve pressure.


Or maybe not, and the scale of the station is enough to build 30km high walls?


Very good point!

Provide a working demo. Your first (and only) video shows me how to buy the engine (!?), then focuses on the asset pipeline and then shows a 2D minesweeper clone above a very generic 3D scene. I'n not too sure that the 3D scene was generated by the engine.


Don't focus on the development pipeline. Anyone that is willing to buy your product will be more than capable of figuring that part out. Make some demos showing the features of the engine. I'm not buying it for the pipeline, I am buying it for what it can do. What can your engine do? I made a simple minesweeper clone many years ago using Windows GDI. I can make a textured and normal mapped cube with OpenGL by downloading one of the plethora on tutorials available online. Point is, cheap or not, I can do this now and for free.


Videos are great, but when I say demos, I mean an actual demo application that I can download that shows what the engine can do. Videos should be instructional. They don't give the same effect as actually playing something built on the engine.

I had that issue as well. I was using shaders to do the blending and I got the blending wrong in the shader.

The ring has mirrored walls to reflect sunlight into the ring and keep the atmosphere from escaping laterally. The atmosphere is held in place by the artificial gravity produced from the rotation of the ring.
