It would be nice if the game was translated into English as my Portuguese is not great. But being a clicker game, it's quite obvious what everything does without being translated.
There are a few gameplay problems in my opinion:
When an item that you can't afford yet is shown, the darkened writing is very hard to see even with the brightness on full, so I don't know how much money to save. This is mostly a problem with 3/8 and M/bi.
When a new item appears in the Upgrades, there is a notification. But there should be a notification when you can afford it, especially due to the problem mentioned above.
The manual click is incredibly under-powered, especially for a game with 'clicker' in the name.
I find it a bit odd that upgrades are available at 1, 5, 10, 50, 75 and 100 of an item but not 25. 10 to 50 is a bit of a big jump.
I don't know if it is mentioned in the game that bulk buying reduces the cost as, like I said, my Portuguese is not too good.
Having played Cookie Clicker, Adventure Capitalist and a few others, I look forward to seeing where this game goes and what the 4th and 5th menus do, I assume that one of them is Prestige.
