When trrying to install on an android device, I recieve the error "App not installed as package appears to be invalid". I was able to make it an APK file, am I missing something before creating it as an APK?

From what I found online this seems to be an issue when you attempt to sideload an APK with a similar package name as an already installed one, it could be possible that you either need to uninstall a previously generated APK, or use a more unique app name/package owner combination
I'll read more about it now but you could try these in the meantime, as well as installing in another phone or an emulator just to be sure
Seems to be caused by a number of things, the biggest ones being install permissions (especially now with the new sideloading restrictions Google implemented) or creating a new APK for the same game with a different keystore than the original. I'd make sure those two things aren't getting in the way before anything
It can also happen because of a corrupted APK, at which point the logs folder can tell you if anything's wrong. You can send me the log files at contact@kagurarpg.com if you want me to take a look for you, but it's more likely one of the things I mentioned above
