As you explain, the game works around a single ratio (3/4), for game design reasons, and so that the game is balanced for everyone.
However, it's true that we haven't tested other ratios, to see if the benefit is negligible or not (or if there is a solution to counterbalance it).
However, in order to make the other ratios work, we need to rework the game interface so that they are compatible with the other resolutions (otherwise, the UI may stretch and have a pretty ugly result).
Nevertheless, we will try to take into account your return for a future project. We underestimated the technical needs of the players, to have a good experience of the game. We will try to improve on that.
Thank you for your message :).
