Thanks for pointing out that bug! I just fixed it and uploaded the new versions.
I'm not actively working on Suzerain now, but I try to fix any bugs that I hear of.
I'm not sure how well gamepad controls will work with the Android version. If you want to test out the free Android version (and don't want to bother with installing the .apk version here), you could try installing it through the Google Play store.
I don't have a discord or any other sort of forum to discuss this game other than here.
Feel free to make YouTube videos of Suzerain!
