2 little things regarding orientation that, I think would be very usefull:
Could you please add the distance (from home/vortex) to the mouse-position. (something like “x km” added to the mouse pointer.)
Could you add an indicator that clearly shows you the direction to home /vortex. (i know you have it on the compass, but I’d like it more direct at placement.)
I’m also thinking of something like “selecting the start and end points and maybe some “via pont(s)” and than pre-incate the optimal route (including from where you’ve advanced), but I’ll better leave that to you !
(At the moment I find it quite difficult to lay belts/pipes/tracks in one go, because I always have to guess where to turn.)
Maybe both of these things could be combined !?
(Of course it’s possible it’s just me missing something here and I know you have the grid cordinates, but that’s very indirect and it requires some calculations. And I’ve only advanced in the game partly. )
Kind regards and my compliments to the developers for creting this enjoyable, puzzle game.
