Thanks to those who've played and rated so far! For those who see this, I'd love thoughts on the time element; is 60 seconds too much?
I find it's way more than needed, but then, you know, I created the puzzles! :p
I feel like it could be reduced to 30 seconds in a future version of the game (which, if me and the team come back to, would probably include shopping centres/malls as a new building and also some new equipment to place!).
