ok so this is now my favourite game, but there's something weird going on with the progression, it says I need 5912 workers to level up to level 4, but the maximum I can get on level 3 is 5600, (also only being able to get 100 gems at a time whilst I'm meant to be earning 800 a game is rather demotivating) so I would suggest rethinking the idea of limiting the about of stuff a player can have. Absolutely LOVE the gameplay though.
