I played it for awhile and then the screen gets kind of cluttered with belts and numbers being produced. At first its mildly interesting to adapt use these numbers in the equations you develop but after awhile the game is just annoying 7th homework that never ends. It might be more interesting if there were very clever ways to highlight new things you're working on and make notes on screen. It would also be nice to be able to easily erase clutter.

Factorio had a nice way to plan things on a cluttered screen. If you laid down a piece of RR track you could then put a train stop on the track. You could then put a note to yourself on the train stop by typing what you needed instead of a town name for the stop. Example "Bring rocket assembly here". Beltex doesn't have that. The hexagons make things difficult. I didn't see what the advantage of hexagons was. Its like the developer thought, "I'll be clever and use hexagons. I'm so clever" and then he didn't notice they were a pain in the ass. You might notice they don't have "pain in the ass" listed in user defined tags. Its because no one wants that. How hard can it be to give users the option of hexagons or squares? I'm guessing its no trouble at all but the dev didn't offer it.

I'd have liked to lay down new belts or proposed belts in different colors to make it easier to find things I'm currently working on. Its very easy for things to get lost in the current game and its tiresome to find the various elements again. After all the reward for getting things done is just another problem to solve.
