I had so much fun with this game but it had a lot of things that could be improved:
the tutorial is a bit overwhelming with the amount of text it dumps on you, and it has some layering issues, I had to restart the level when I put one of the servers under it.
its very hard to tell what mode youre one(wire/switch/delete)
I felt no way to optimize the price beyond fill switches as much as you can, which isnt that difficult.
The whole concept of packet loss was not explained at all and as far as I'm aware its entirely mistakes the network makes before it learns the right paths.
There needs to be a way to reset the stage without leaving and entering it again.
And lastly, nothing stops me from selling all the parts connected to devices that have finished their tasks already to reduce the costs.
