So much digging for so little profit and then I have to go AAAAAAALLLLLL the way back to base? And just as I saw some diamonds I went "too deep" and have to find $500 worth of ore just to go get the good stuff? Good premise, but seriously overbalanced towards the painfully tedious.
Sometimes the selection seems to get "stuck" - I can move my mouse all over the puzzle and onto other bridges but the bridge I just created stays selected and if I click it affects that bridge, not whatever I'm actually hovering over. This seems to happen every other game or so for a few seconds at a time.
I like the feature where it highlights all of a certain number. However, I'm also primarily a keyboard user and really want to be able to use my arrow keys to get around the grid! I hate having to use the mouse unnecessarily.
