Talking about it, i already paid 2$ previously, is there i way to "upgrade" it to the 5$ with 3$ ? or do i have to buy it again for 5 ?
Good :) We appreciate any kind of support to develop the game. We know nobody likes paying more or paying twice for the "same" thing (it's not the same thing, there is always new content and the new content always requires work) .
That's why we try to offer different options, and the player decides which is better for him :)
