I have the same issue when starting the game. Start commands to set it to "windowed" don't do anything, it is stretched over 1,5 screens and I cannot select anything.

I am having the same issue since the last patch. Please fix

I wrote support and they told me:

In order to solve this, you have to delete the Kingdom Rush Alliance file in %appdata% and you also have to delete the game and reinstall it.

After this, you can change the image quality of the game by going to Options that appear on the top left corner of the main screen of the game and choosing "Full HD" as image quality

Did not work for me, but I did not put much energy in it yet. Might write them again, just thought to let you know.

You can change the settings manually.
If you have Windows go to:
"C:\Users\YourWindowsUserName\AppData\Roaming\kingdom_rush_alliance"
There should be the file "settings.lua", open it with Notepad and try to change the tag "fullscreen" to "true".

I only got cache, global and slot_1 as .lua files and none of them contain screen sizes, sadly (and obviously). Daheck did I screw up?

I checked the rest of Kingdom Rush titles and their respective folders - they all have "settings.lua" file except Vengeance. Vengeance has "config.plist" file which is in "Local" folder instead of "Roaming".
Maybe, it is worth to try to verify files or reinstall the game.

The posted fix did not work for me either.

I'm having this same issue.

I managed to fix the problem by using Tab to get into the game settings. It was the only way, I tried everything but this simple trick worked. Basically, you just need to go to the game screen where the music plays and the background image shows up, and press Tab until the outline disappears. When it does, you’re probably hovering over options. Then, hit Enter. It should open the settings. Keep pressing Tab until you find the video settings, and change to the resolution you want. If you still can't do it in the settings screen, just select a lower resolution so you can move the mouse around easier and adjust things the way you need.

Alright So i found the Fix. You just need to open the settings in game and press tab until you hit the resolution tab and click on a smaller resolution or fullscreen.
