The brightness, contrast and things like that are perfect, you put a lot of good work into it. It reminds me of Brogue. I'm talking about font size only, especially reading tiny text messages. But if you wanted single screen game, then there is not much helping it I guess. However it doesn't take all screen on my resolution, which is 1280x1024, so maybe it is possible to do something. I tried to scale the window like in some flash games by pressing CTRL+mouse wheel up, but it didn't do anything. So I tried lowering desktop resolution to 1024x768. It is a bit better, but still hard to read.
