Text against background could be much more contrasting, i.e. make the background lighter or the text darker. I understand you want to get the inverted text at the start, so it can't be too dark. But darker would be better.
Sort of see why wards are tricky; you have to stand out both against the light background and the dark blue. I was thinking of a light green(maybe even the green ward color), but it also wouldn't kill you to just make the dots bigger. If you had a higher resolution, you could even just make them mini green ward icons. Purple seems like a terrible color to me though; it's exactly between red and blue, so it doesn't stand out against either of the colors you're using.
You could also switch the blue side walls to be the dark blue, to match your dark red, and make the bushes a lighter, non-blue color that stands out from the blue background.
Other(non color) stuff:
Your key is below all the maps, but you need to see the key to understand the maps(or, you don't need it at all if you made really good choices that are obvious to anyone).
Completely missed the fine print under the maps on the first read through, should stand out more; I think it's cause you made the font size too small.
Silhouettes take like 2 seconds to decipher on some of them; you could just use the actual icons.
good luck, you'll need it
them under our own tower >:)
