Thanks - yes, needs a lot of work, my apologies. TBH it's more like a tech demo than a game. I realise the tile dragging doesn't seem to work on mobile devices through a browser. Once the embargo finishes I will look at updating!
Thanks, I did put a delay on the drag so the tiles didn't move when you only wanted to click them - perhaps this is not well calibrated across all environments because it runs off the Update function so is related to frame rate - it seemed to work on mine but may well need further testing.
