Hey, thanks for reporting
By the 'config window' do you mean Unity's config window which pops up after you run the game?
Also, what kind of gamepad do you use? I've tested Playstation and Xbox controllers so far - both worked well.
Anyway, I did notice the latest update so far, so I installed the latest version and at first it did run.
It ran at 720p windowed with low quality and I again had my gamepad in XInput mode connected. First issue then was how the guy kept moving to the lower right; He did react to moving the d-pad and left stick, but when I let go, he'd keep moving lower right again. Also the buttons didn't seem to be mapped ?(
I did, however, find the pause button and the pause menu showed me the graphics settings which I set to 1080p high quality fullscreen right away; Then I closed the game to reconnect the gamepad and reopened it. But now, with graphics at 1080p HQ full, it keeps crashing on me again everytime I try starting a new game. I tried reopening it several times with and without gamepad and it still crashed upon tryna start a new game.
So I tried to delete and reinstall the game's latest version in hopes it would reset graphics, but it's still at 1080p HQ full and now, for the second issue, I can't for the love of me seem to find the config file that has the graphics settings written in it.
Hey, as I mentioned before - I am currently focusing on developing core game experience and cannot support your controller (but it's on my TODO list and will be done in the future).
Regarding your settings issue: if you are on Windows, you can go and delete all the content from this folder C:\Users\YOUR_USER_NAME\AppData\LocalLow\WolkGames\
If you are on Mac, go to ~/Library/Preferences folder, and delete a file named unity.WolkGames.TurboIslandPurger.plist
It should clear the saved graphic settings
