I was about to give this game a 5 stars after reaching the end, but then, sadly, it bugged, just after getting the perk Improved Efficicency at lvl 19.
Now the game is freezed. I can't buy any more building as the only one available is some ''Test tube tangerines'' for 10 000 000 000t each. I can't even click to get more tanjerines (anyway it would take years to get that much).
I googled it wondering if I was the only one : I'm not. Sadly nothing is done!
Please please please fix this bug! I love the game.
