The game idea is really good, and I think that it could keep you engaged for longer because at some point the game just becomes impossible, as a connection spawns that is either impossible or that can impossibly be completed in time, as you have to restructure multiple connections. I think it would be nice if the time to complete a connection where to scale the more factories you have. I also think it would be cool if you could link up multiple conveyor belts into one. The base idea is really good and with a bit of time this idea could really flourish into something special!
