Sad to say, but I didn't get at all how it works the first time, so I brute-forced it to the end. So, then I read tutorial and tried it again, and now, understanding it more, but still not completely:
- First level doesn't really teach me anything, I just left-click and instantly win
- Adding to the first point , it would be nice to see where each cube is pointing before they're properly connected
- I guess that the lines between cubes and walls can't cross, that needs some indication too
- But then again, for the last level solution the lines are crossing, so maybe I'm wrong
- Blue color changes to teal on connection, made me confused as I thought it was some color combination mechanic
Overall, it seems like simple but interesting idea, I just didn't fully understand it.
