Thank you for your feedback!
I wanted to play more with packet loss, like on some levels I wanted to add events such as a switch dies randomly and you cannot edit anything after you start the time and it still needs to complete. So, they are somewhat unused counters now and waiting for more features. :D
Also, more tutorials were on my to-do list but got cut. (With less text on each one)
And the UI is supposed to light up when a tool is selected, it's a bug I think.
I think you found a way to optimize costs. :D I wanted the game to stop letting you editing when time is running and reset the level when stopped.
