Suggestion: Maybe allow us to build 'supports' or something over a ruins so we can build in that slot, my islands look a little bit weird with these tall towers and then a gap.
Game is brilliant.. I highly suggest you play it and stick around, it has so much potential and is brilliant the way it is.. Runs well on any machine and is super fast! 5/5 The game is very addicting, once you start you cant stop!
Damn nevermind, that's the cash cap, but trust me, it's there for a reason, nothing costs more then the cap, you just have to max every cash thing out then move onto diamonds.
Played for a few hours until I realised it doesn't save and lost everything, good game but this spoilt it for me on so many levels. 1/5 until it's fixed.
You can actually build over ruins between two other buildings. :)
