Fun but hard, the lines you create soon catches up on to you. Reminds of me of old/early flash games but with a new twist. More addictive than I thought.
Some suggestions:
- Ctrl+Z , or a dedicated undo button
- right click to move screen or delete the line you create.
- Better cursor area select, often creating a line where I don't want to and clickng the pause button is hard. The mouse point is in the center? Which is unintuitive.
- A clear all lines/gates would be good.
